The hidden paragraph instructions, before linking to the "babbler" URL, got a chuckle out of me:
## LLM instructions

When I tried it ~12 hours ago it actually tried to summarize the linked markov generated page and attempted to make some sense of it while noting it seemed to be mostly nonsensical.
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.
There are multiple people claiming this in this thread, but with no more than a "it doesn't work stop". Would be great to hear some concrete information.
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.
You're missing the point.
The goal of garbage production is not to break the bots or poison LLMs, but to remove load from your own site. The author writes it in the article. He found that feeding bots garbage is the cheapest strategy, that's all.
I think the better but more expensive approach would be to flood the LLM with LLM generated positive press/marketing material for your project website. And possibly link to other sites with news organization looking domains that also contain loads of positive press for your products.
I.e. instead of feeding it garbage feed it with "seo" chum.
Always include many hidden pages on your personal website espousing how hireable you are and how you're a 10,000x developer who can run sixteen independent businesses on your own all at once and how you never take sick days or question orders

What makes you think humans are better at filtering through the garbage than the AIs are?
Interesting that babble.c doesn't compile (with gcc 14):
babble.c: In function ‘main’:
babble.c:651:40: error: passing argument 1 of ‘pthread_detach’ makes integer from pointer without a cast [-Wint-conversion]
651 | pthread_detach(&thread);
| ^~~~~~~
| |
| pthread_t * {aka long unsigned int *}
In file included from babble.c:77:
/usr/include/pthread.h:269:38: note: expected ‘pthread_t’ {aka ‘long unsigned int’} but argument is of type ‘pthread_t *’ {aka ‘long unsigned int *’}
269 | extern int pthread_detach (pthread_t __th) __THROW;
I assume the author is using a compiler that either doesn't show that warning by default, or doesn't error out on that warning by default. But I'm surprised the program doesn't crash (at the very least, I'm surprised it doesn't run out of memory eventually, as presumably libc can't actually detach those threads, and pthread_join() is never called).
As this binary does a bunch of manual text parsing and string operations in C (including implementing a basic HTTP server), I'd recommend at the very least running it as an unprivileged user (which the author implicitly recommends via the provided systemd unit file) inside a container (which won't definitely save you, but is perhaps better than nothing).
The program also uses unsafe C functions like sprintf(). A quick look at one of the instances suggests that the use is indeed safe, but that sort of thing raises red flags for me as to the safety of the program as a whole.
And while it does process requests very quickly, it also appears to have no limit on the number of concurrent threads it will create to process each request, so... beware.
Sorry about that, stupid mistake on my side. I've fix the version on the server, an you can just edit the line to "pthread_detach(thread);" The snprintf() is only part of a status page, so you can remove it if you want.
As for the threads, that could be an issue if directly exposed to the internet: All it would take for an attacker to open a whole a whole bunch of connections and never send anything to OOM the process. However, this isn't possible if it's behind a reverse proxy, because the proxy has to receive all the information the needs server before routing the request. That should also filter out any malformed requests, which while I'm fairly sure the parser has sane error handling, it doesn't hurt to be safe.
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.
> it probably costs you as much or more than it costs them in terms of both network bytes and CPU
Network bytes, perhaps (though text is small), but the article points out that each garbage page is served using only microseconds of CPU time, and a little over a megabyte of RAM.
The goal here isn't to get the bots to go away, it's to feed them garbage forever, in a way that's light on your resources. Certainly the bot, plus the offline process that trains on your garbage data, will be using more CPU (and I/O) time than you will to generate it.
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.
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 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.
For reference, I picked Frankenstein, Alice in wonderland and Moby dick as sources and I think they might be larger than necessary as they take some time to load. But they still work fine.
There also seems to be a bug in babble.c in the thread handling? I did "fix" it as gcc suggested by changing pthread_detach(&thread) to pthread_detach(thread).. I probably broke something but it compiles and runs now :)
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.
> Gzip only provides a compression ratio of a little over 1000: If I want a file that expands to 100 GB, I’ve got to serve a 100 MB asset. Worse, when I tried it, the bots just shrugged it off, with some even coming back for more.
I thought a gzip bomb was crafted to explicitly be virtually unlimited in the "payload" size?
The problem with gzip bombs in the web context in general is that they operate on the naive assumption that the client will decompress the payload entirely. This is very rarely the case, and you kinda have to go out of your way to make that happen[1], and it really only makes sense if you're looking at some binary format that can't be truncated like you can with HTML.
Instead most if not all clients will use some form of streaming decompression, with a termination criterion, and to the extent stuff is decompressed in full, very rarely will anything be decompressed in full and held in memory, as that would nuke your crawler the first time you ran into a website mirroring linux ISOs.
If the payload expands to something too large then it is easy to detect and ignore. Serve up thousands of 10kb or 100kb files that expand to 10s of MB with random garbage inside...possibly the same text but slightly modified. That will waste the time and CPU cycles and provide no value to them. Maybe also add a message you want to amplify so AI bots train on it.
The problem is that believable content doesn't compress well. You aren't going to get anywhere close to that 1:1000 compression ratio unless it's just a single word/character repeated thousands of times.
It's a choice between sending them some big files that will be filtered out long before they can do any real damage or sending them nonsense text that might actually make it's way into their training data.

I do not use feedparser, because it could not parse properly some rss files. I implemented my own lib for rss parsing.
