I have yet to see any bots figure out how to get past the Basic Auth protecting all links on my (zero traffic) website. Of course, any user following a link will be stopped by the same login dialog (I display the credentials on the home page).
The solution is to make the secrets public. ALL websites could implement the same User/Pass credentials:
User: nobots
Pass: nobots
Can bot writers overcome this if they know the credentials?
> Can bot writers overcome this if they know the credentials?
Yes, instead of doing just a HTTP request, do a HTTP request with authentication, trivial really. Probably the reason they "can't" do that now is because they haven't came across "public content behind Basic Auth with known correct credentials", so the behavior hasn't been added. But it's literally loading http://username:password@example.com instead of http://example.com to use Basic Auth, couldn't be simpler :)
The technical side is straightforward but the legal implications of trying passwords to try to scrape content behind authentication could pose a barrier. Using credentials that aren't yours, even if they are publicly known, is (in many jurisdictions) a crime. Doing it at scale as part of a company would be quite risky.
The people in the mad dash to AGI are either driven by religious conviction, or pure nihilism. Nobody doing this seriously considers the law a valid impediment. They justify (earnestly or not) companies doing things like scraping independent artist’s bread and butter work to create commercial services that tank their market with garbage knockoffs by claiming we’re moving into a post-work society. Meanwhile, the US government is moving at a breakneck pace to dismantle the already insufficient safety nets we do have. None of them care. Ethical roadblocks seem to be a solved problem in tech, now.
> but the legal implications of trying passwords to try to scrape content behind authentication could pose a barrier
If you're doing something alike to cracking then yeah. But if the credentials are right there on the landing page, and visible to the public, it's not really cracking anymore since you already know the right password before you try it, and the website that put up the basic auth is freely sharing the password, so you aren't really bypassing anything, just using the same access methods as everyone else.
Again, if you're stumbling upon basic auth and you try to crack them, I agree it's at least borderline illegal, but this was not the context in the parent comment.
(a) Violations Regarding Circumvention of Technological Measures.—
(1)
(A) No person shall circumvent a technological measure that effectively controls access to a work protected under this title.
This has been used by car manufacturers to deny diagnostic information even though the encryption key needed to decrypt the information is sitting on disk next to the encrypted data. That's since been exempted for vehicle repairs but only because they're vehicle repairs, not because the key was left in plain view.
If you are only authorized to access it under certain conditions, trying to access it outside those conditions is illegal (in the US, minimally). Gaining knowledge of a password does not grant permission to use it.
Huh, that's interesting, I'm not too familiar with US law, so not surprising I didn't know that :) Time to lookup if it works similarly in my country today, last time I was involved with anything slightly related to it was almost two decades ago, and at that point we (as a company with legal consul) made choices that assumed public info was OK to use, as it was public (paraphrased from memory), but might look differently today.
Otoh if, as a human, you use a known (even leaked on the website) password to "bypass the security" in order to "gain access to content you're not authorized to see", I think you'd get in trouble. I'd like if the same logic aplied to bots - implement basic (albeit weak) security and only allow access to humans. This way bots have to _hack you_ to read the content
> you use a known (even leaked on the website) password to "bypass the security" in order to "gain access to content you're not authorized to see", I think you'd get in trouble
I agree, but if someone has a website that says "This isn't the real page, go to /real.html and when authentication pops up, enter user:password", then I'd argue that is no longer "gaining access to content you're not authorized to see", the author of the page shared the credentials themselves, and acknowledged they aren't trying to hide anything, just providing a non-typical way of accessing the (for all intents and purposes, public) content.
The law doesn't directly stop anyone from doing anything, it acts much differently from a technical control. The law provides recourse to people hurt by violations and enables law enforcement action. I suspect Meta has since stopped their torrenting, and may lose the lawsuit they current face. Anyone certainly could log in to any site with credentials that are not their own, but fear of legal action may deter them.
The (theoretical) scenario is: There is a website (example.com) that publishes the correct credentials, and tells users to go to example.com/authenticate and put those there.
At no point is a user (or bot) bypassing anything that was meant to stop them, they're following what the website is telling them publicly.
I think this analysis is correct. The part you're missing from my comment is "at scale", which means trying to apply this scraping technique to other sites. As a contract security engineer I've found all kinds of accidentally leaked credentials; knowing if a set of credentials is accidentally leaked or are being intentionally disclosed to the public feels like a human-in-the-loop kind of thing. Getting it wrong, especially when automated at scale, is the context the bot writer needs to consider.
There’s hundreds of billions of dollars behind these guys. Not only that, but they also have institutional power backing them. The laws don’t really matter to the worst offenders.
Similar to OPs article, trying to find a technical solution here is very inefficient and just a bandaid. The people running our society are on the whole corrupt and evil. Much simpler (not easier) and more powerful to remove them.
The bot protection on low traffic sites can be hilarious in how simple and effective it can be. Just click this checkbox. That's it. But it's not a check box matching a specific pattern provided by a well-known service, so until the bot writer inspects the site and adds the case it'll work. A browser running openai operator or whatever its called would immediately figure it out though.
> A browser running openai operator or whatever its called would immediately figure it out though.
But running that costs money, which is a disincentive. (How strong of a disincentive depends on how much it costs vs. the estimated value of a scraped page, but I think it would 100x the per-page cost at least.)
Really cool. Reminds me of farmers of some third world countries. Completely ignored by government, exploited by commission brokers, farmers now use all sorts of tricks, including coloring and faking their farm produce, without regard for health hazards to consumers. The city dwellers who thought they have gamed the system through high education, jobs and slick-talk, have to consume whatever is served to them by the desperate farmers.
The agricultural farmers did it to themselves, many are very wealthy already. Anything corporate America has taken over is because the farmers didn’t want to do the maintenance work. So they sell out to big corporations who will make it easier.
Same as any other consumer using Meta products. You sell out because it’s easier to network that way.

I have always recommended this strategy: flood the AI bots with garbage that looks like authentic information so that they need actual humans to filter the information. Make sure that every site does this so they get more garbage than real stuffs. Hike up the proportion so that even ordinary people eventually figure out that using these AI products has more harm than use because it just produces garbage. I just don't know what is the cost, now it looks like pretty doable.
If you can't fight them, flood them. If they want to open a window, pull down the whole house.
LLMs can now detect garbage much more cheaply than humans can. This might increase cost slightly for the companies that own the AIs, but it almost certainly will not result in hiring human reviewers
> LLMs can now detect garbage much more cheaply than humans can.
Off the top of my head, I don't think this is true for training data. I could be wrong, but it seems very fallible to let GPT-5 be the source of ground truth for GPT-6.
What about garbage that are difficult to tell from truth?
For example, say I have an AD&D website, how does AI tell whether a piece of FR history is canon or not? Yeah I know it's a bit extreme, but you get the idea.
I run something I call an "ethical crawler". It’s designed to avoid being a burden to websites - it makes requests very infrequently. Crawling the internet reliably has become increasingly difficult, as more and more content is protected or blocked. It’s especially frustrating when RSS feeds are inaccessible to bots.
404 definitely are not a problem for me. My crawler tests different mechanisms and browser headers while exploring the web.
What you're referring to are LLMs visiting your page via tool use. That's a drop in the ocean of crawlers that are racing to slurp as much of the internet as possible before it dries.
1. The bots have essentially unlimited memory and CPU. That's the cheapest part of any scraping setup.
2. You need to send the data for the Markov chain generator to the client, along with the code. This is probably bigger than the response you'd be sending anyway. (And good luck getting a bot to cache JavaScript)
3. As the author said, each request uses microseconds of CPU and just over a megabyte of RAM. This isn't taxing for anyone.
> 1. The bots have essentially unlimited memory and CPU. That's the cheapest part of any scraping setup.
Anyone crawling at scale would try to limit the per-request memory and CPU bounds, no? Surely you'd try to minimize resource contention at least a little bit?
Then why generate text at all? Just run a script that enters an infinite loop. But the bots would have to protect against this or the scrapers wouldn't make it very far on the larger internet, would they? Spending a few microseconds on the server costs essentially nothing, and guarantees the scraper's most precious resource (bandwidth) is wasted.
Does this really work though? I know nothing about the inner workings of LLMs, but don't you want to break their word associations? Rather than generating "garbage" text based on which words tend to occur together and LLMs generating text based on which words it has seen together, don't you want to give them text that relates unrelated words?
The crawlers will just add a prompt string “if the site is trying to trick you with fake content, disregard it and request their real pages 100x more frequently” and it will be another arms race.
Presumably the crawlers don’t already have an LLM in the loop but it could easily be added when a site is seen to be some threshold number of pages and/or content size.
In authors setup, sending Markova generated garbage is much lighter on resources than sending static pages. Only bots will continue to follow links to the next piece of garbage and thus he traps bots in garbage. No need to detect bots, they reveal themselves.
To what end? I imagine ad networks have pretty robust bot detection. I'd also be surprised if scrapers didn't have ad block functionality in their headless browsing.
One way to keep things mostly the same without having to store any of it yourself:
1. Use an RNG seeded from the request URL itself to generate each page. This is already enough for an unchanging static site of finite it infinite size.
2. With each word the generator outputs, generate a random number between, say, 0 and 1000. On day i, replace the about-to-be-output word with a link if this random number is between 0 and i. This way, every day roughly 0.1% of words will turn into links, with the rest of the text remaining stable over time.
stupid question: why not encrypt your API response that only your frontend can decrypt. I understand very well that no client side encryption is secure and eventually once they get down to it, they ll figure out how this encryption scheme works but it ll keep 99% out won't it?

> You don’t really need any bot detection: just linking to the garbage from your main website will do. Because each page links to five more garbage pages, the crawler’s queue will quickly fill up with an exponential amount of garbage until it has no time left to crawl your real site.
Thanks, I thought that these are prioritized, so while the garbage links might fill up the queue, they'd do so only after all real links are visited, so the server load is the same. But of course, not all/most bots might be configured this way.
> If a link is posted somewhere, the bots will know it exists,
It's not clear that they are doing that. Web logs I've seen from other writing on this topic show them re-crawling the same pages at high rates, in addition to crawling new pages
it does at a macroscopic level by making scraping expensive. If every "valid" page is scattered at random amongst a tarpit of recursive pages of nonsense, it becomes computationally and temporaly expensive to scrape a site for "good" data.
A single site doing this does nothing. But many sites doing this has a severe negative impact on the utility of AI scrapers - at least, until a countermeasure is developed.
My initial reaction was that running something like this is still a loss, because it probably costs you as much or more than it costs them in terms of both network bytes and CPU. But then I realised two things:
1. If they are using residential IPs, each byte of network bandwidth is probably costing them a lot more than it's costing you. Win.
2. More importantly, if this became a thing that a large fraction of all websites do, the economic incentive for AI scrapers would greatly shrink. (They don't care if 0.02% of their scraping is garbage; they care a lot if 80% is.) And the only move I think they would have in this arms race would be... to use an LLM to decide whether a page is garbage or not! And now the cost of scraping a page is really starting to increase for them, even if they only run a local LLM.
We should encourage number 2. So much of the content that the AI companies are scraping is already garbage, and that's a problem. E.g. LLMs are frequently confidently wrong, but so is Reddit, who produce a large volume of trading data. We've seen a study surgesting that you can poison an LLM with very little data. Encouraging the AI companies to care about the quality of the data they are scraping could be beneficial to all.
The cost of being critical of source material might make some AI companies tank, but that seems inevitable.
Not to mention they have to store the data after they download it. In theory storing garbage data is costly to them. However I have a nagging feeling that the attitude of these scrapers is they get paid the same amount per gigabyte whether it's nonsense or not.
If they even are AI crawlers. Could be just as well some exploit-scanners that are searching for endpoints they'd try to exploit. That wouldn't require storing the content, only the links.
If you look at the pages which are hit and how many pages are hit by any one address in a given period of time it's pretty easy to identify features which are reliable proxies for e.g. exploit scanners, trawlers, agents. I publish a feed of what's being hit on my servers, contact me for details (you need to be able to make DNS queries to a particular server directed at a domain which is not reachable from ICANN's root).
I'm not sure requestcatcher is a good one, it's just the first one that came up when I googled. But I guess there are many such services, or one could also use some link shortener service with public logs.
You can easily generate a number of random images with ImageMagick and serve these as part of the babbled text. And you could even add text onto these images so image analyzers with OCR will have "fun" too.
Example code:
for c in aqua blue green yellow ; do
for w in hello world huba hop ; do
magick -size 1024x768 xc:$c -gravity center -annotate 0 $w /tmp/$w-$c.jpeg
done
done
Do this in a loop for all colors known to the web and for a number of words from a text corpus, and voila, ... ;-)
I think random text can be detected and filtered. We need probably pre-generated bad information to make utility of crawling one's site truly negative.
On my site, I serve them a subset of Emergent Misalignment dataset, randomly perturbed by substituting some words with synonyms.
The user's approach would work only if bots can accurately even be classified, but this is impossible. The end result is that the action is user's site is now nothing but markov garbage. Not only will bots desert it but humans will too.
I bet the next generation approach, if the crawlers start using CSS, is "if you're a human, don't bother clicking this link lol". And everyone will know what's up.
The 0px rule would be in a separate .CSS file. I doubt that bots load .CSS files for .html files, at least I don't remember seeing this in my server logs.
And another "classic" solution is to use white link text on white background, or a font with zero width characters, all stuff which is rather unlikely to be analysed by a scraper interested primarily in text.
Ideally it would require rendering the css and doing a check on the Dom if the link is 0 pixels wide. But once bots figure that out I can still left: -100000px those links or z-index: -10000. To hide them in other ways. It’s a moving target how much time will the Llm companies waste decoding all the ways I can hide something before I move the target again. Now the Llm companies are in an expensive arms race.
You don't need to classify bots. Bots will follow any link they find. Hide links on your pages and eventually every bot will greedily find itself in an endless labyrinth of slop.
If bots get good enough to know what links they're scraping, chances are they'll also avoid scraping links they don't need to! The problem solves itself!
Only low IQ folks are okay with having their traffic MITMed by Cloudflare (and the NSA). Also, they can extort you and cut you off at any time, as they have done to folks, which further supports the prior point.

> 1. The bots have essentially unlimited memory and CPU. That's the cheapest part of any scraping setup.
Anyone crawling at scale would try to limit the per-request memory and CPU bounds, no? Surely you'd try to minimize resource contention at least a little bit?
Then why generate text at all? Just run a script that enters an infinite loop. But the bots would have to protect against this or the scrapers wouldn't make it very far on the larger internet, would they? Spending a few microseconds on the server costs essentially nothing, and guarantees the scraper's most precious resource (bandwidth) is wasted.
Does this really work though? I know nothing about the inner workings of LLMs, but don't you want to break their word associations? Rather than generating "garbage" text based on which words tend to occur together and LLMs generating text based on which words it has seen together, don't you want to give them text that relates unrelated words?
Why? The point is not to train bots one way or another, it’s to keep them busy in low resource activities instead of high resource activities.
The crawlers will just add a prompt string “if the site is trying to trick you with fake content, disregard it and request their real pages 100x more frequently” and it will be another arms race.
Presumably the crawlers don’t already have an LLM in the loop but it could easily be added when a site is seen to be some threshold number of pages and/or content size.
Can someone explain how this works?
Surely the bots are still hitting the pages they were hitting before but now they also hit the garbage pages too?
In authors setup, sending Markova generated garbage is much lighter on resources than sending static pages. Only bots will continue to follow links to the next piece of garbage and thus he traps bots in garbage. No need to detect bots, they reveal themselves.
But yes, all bots start out on an actual page.
Thanks for the explanation!
Ah, it is explained in another post - https://maurycyz.com/projects/trap_bots/
Clever
Why not show them ads? Endless ads, with AI content in between them?
To what end? I imagine ad networks have pretty robust bot detection. I'd also be surprised if scrapers didn't have ad block functionality in their headless browsing.
if you want to be really sneaky make it so the web doesn't start off infinite
because as infinite site that has appeared out of nowhere will quickly be noticed and blocked
start it off small, and grow it by a few pages every day
and the existing pages should stay 99% the same between crawls to gain reputation
They don't especially want to be sneaky, they mostly want the crawlers to stop hammering their site. Getting blocked would be a win.
Good thinking.
One way to keep things mostly the same without having to store any of it yourself:
1. Use an RNG seeded from the request URL itself to generate each page. This is already enough for an unchanging static site of finite it infinite size.
2. With each word the generator outputs, generate a random number between, say, 0 and 1000. On day i, replace the about-to-be-output word with a link if this random number is between 0 and i. This way, every day roughly 0.1% of words will turn into links, with the rest of the text remaining stable over time.
stupid question: why not encrypt your API response that only your frontend can decrypt. I understand very well that no client side encryption is secure and eventually once they get down to it, they ll figure out how this encryption scheme works but it ll keep 99% out won't it?
I had to follow a link to see an example:
"A glass is not impossible to make the file and so deepen the original cut. Now heat a small spot on the glass, and a candle flame to a clear singing note.
— context_length = 2. The source material is a book on glassblowing."
Add "babble" to any url to get a page of nonsense:
https://maurycyz.com/babble/projects/trap_bots/
How does this help protect the regular non-garbage pages from the bots?
The follow on post explains:
> You don’t really need any bot detection: just linking to the garbage from your main website will do. Because each page links to five more garbage pages, the crawler’s queue will quickly fill up with an exponential amount of garbage until it has no time left to crawl your real site.
From: https://maurycyz.com/projects/trap_bots/
Thanks, I thought that these are prioritized, so while the garbage links might fill up the queue, they'd do so only after all real links are visited, so the server load is the same. But of course, not all/most bots might be configured this way.
> If a link is posted somewhere, the bots will know it exists,
How would the links be prioritized? If the bots goal is to crawl all content would they have prioritization built-in?
How would they prioritize things they haven't crawled yet?
It's not clear that they are doing that. Web logs I've seen from other writing on this topic show them re-crawling the same pages at high rates, in addition to crawling new pages
it does at a macroscopic level by making scraping expensive. If every "valid" page is scattered at random amongst a tarpit of recursive pages of nonsense, it becomes computationally and temporaly expensive to scrape a site for "good" data.
A single site doing this does nothing. But many sites doing this has a severe negative impact on the utility of AI scrapers - at least, until a countermeasure is developed.
Is there a Markov Babbler based on PHP or something else easy hostable?
I want to redirect all LLM-crawlers to that site.
My initial reaction was that running something like this is still a loss, because it probably costs you as much or more than it costs them in terms of both network bytes and CPU. But then I realised two things:
1. If they are using residential IPs, each byte of network bandwidth is probably costing them a lot more than it's costing you. Win.
2. More importantly, if this became a thing that a large fraction of all websites do, the economic incentive for AI scrapers would greatly shrink. (They don't care if 0.02% of their scraping is garbage; they care a lot if 80% is.) And the only move I think they would have in this arms race would be... to use an LLM to decide whether a page is garbage or not! And now the cost of scraping a page is really starting to increase for them, even if they only run a local LLM.
We should encourage number 2. So much of the content that the AI companies are scraping is already garbage, and that's a problem. E.g. LLMs are frequently confidently wrong, but so is Reddit, who produce a large volume of trading data. We've seen a study surgesting that you can poison an LLM with very little data. Encouraging the AI companies to care about the quality of the data they are scraping could be beneficial to all.
The cost of being critical of source material might make some AI companies tank, but that seems inevitable.
Not to mention they have to store the data after they download it. In theory storing garbage data is costly to them. However I have a nagging feeling that the attitude of these scrapers is they get paid the same amount per gigabyte whether it's nonsense or not.
If they even are AI crawlers. Could be just as well some exploit-scanners that are searching for endpoints they'd try to exploit. That wouldn't require storing the content, only the links.
If you look at the pages which are hit and how many pages are hit by any one address in a given period of time it's pretty easy to identify features which are reliable proxies for e.g. exploit scanners, trawlers, agents. I publish a feed of what's being hit on my servers, contact me for details (you need to be able to make DNS queries to a particular server directed at a domain which is not reachable from ICANN's root).

Eh? That's the speed of an old-school spinning hard disk.
How about adding some image with a public http logger url like
https://ih879.requestcatcher.com/test
to each of the nonsense pages, so we can see an endless flood of funny requests at
https://ih879.requestcatcher.com
?
I'm not sure requestcatcher is a good one, it's just the first one that came up when I googled. But I guess there are many such services, or one could also use some link shortener service with public logs.
You can easily generate a number of random images with ImageMagick and serve these as part of the babbled text. And you could even add text onto these images so image analyzers with OCR will have "fun" too.
Example code:
Do this in a loop for all colors known to the web and for a number of words from a text corpus, and voila, ... ;-)Edit: added example
I think random text can be detected and filtered. We need probably pre-generated bad information to make utility of crawling one's site truly negative.
On my site, I serve them a subset of Emergent Misalignment dataset, randomly perturbed by substituting some words with synonyms.
It should make the LLMs trained on it behave like dicks according to this research https://www.emergent-misalignment.com/
The user's approach would work only if bots can accurately even be classified, but this is impossible. The end result is that the action is user's site is now nothing but markov garbage. Not only will bots desert it but humans will too.
The traditional approach is a link to the tarpit that the bots can see but humans can't, say using CSS to render it 0 pixels in size.
Please keep in mind that not all humans interact with web pages by "seeing". If you fool a scraper you may also fool someone using a screen reader.
I bet the next generation approach, if the crawlers start using CSS, is "if you're a human, don't bother clicking this link lol". And everyone will know what's up.
AI bots try to behave as close to human visitors as possible, so they wouldn't click on 0px wide links, would they?
And if they would today, it seems like a trivial think to fix - just don't click on incorrect/suspicious links?
The 0px rule would be in a separate .CSS file. I doubt that bots load .CSS files for .html files, at least I don't remember seeing this in my server logs.
And another "classic" solution is to use white link text on white background, or a font with zero width characters, all stuff which is rather unlikely to be analysed by a scraper interested primarily in text.
Ideally it would require rendering the css and doing a check on the Dom if the link is 0 pixels wide. But once bots figure that out I can still left: -100000px those links or z-index: -10000. To hide them in other ways. It’s a moving target how much time will the Llm companies waste decoding all the ways I can hide something before I move the target again. Now the Llm companies are in an expensive arms race.
You don't need to classify bots. Bots will follow any link they find. Hide links on your pages and eventually every bot will greedily find itself in an endless labyrinth of slop.
It won't be long before generalized bots stop requesting links that don't have a visually rendered link in a page.
If bots get good enough to know what links they're scraping, chances are they'll also avoid scraping links they don't need to! The problem solves itself!
lets go! nice
What’s wrong with just using cloudflare?

Only low IQ folks are okay with having their traffic MITMed by Cloudflare (and the NSA). Also, they can extort you and cut you off at any time, as they have done to folks, which further supports the prior point.
