I check if a user agent has gptbot, and if it does I 302 it to web.sp.am.

Some details. One of the major players doing the tar pit strategy is Cloudflare. They're a giant in networking and infrastructure, and they use AI (more traditional, nit LLMs) ubiquitously to detect bots. So it is an arms race, but one where both sides have massive incentives.

Making nonsense is indeed detectable, but that misunderstands the purpose: economics. Scraping bots are used because they're a cheap way to get training data. If you make a non zero portion of training data poisonous you'd have to spend increasingly many resources to filter it out. The better the nonsense, the harder to detect. Cloudflare is known it use small LLMs to generate the nonsense, hence requiring systems at least that complex to differentiate it.

So in short the tar pit with garbage data actually decreases the average value of scraped data for bots that ignore do not scrape instructions.

When I was a kid I thought computers would be useful.

I've suggested things like this before. Scrapers grab data to train their models. So feed them poison.

Things like counter factual information, distorted images / audio, mislabeled images, outright falsehoods, false quotations, booby traps (that you can test for after the fact), fake names, fake data, non sequiturs, slanderous statements about people and brands etc.. And choose esoteric subjects to amplify the damage caused to the AI.

You could even have one AI generate the garbage that another ingests and shit out some new links every night until there is an entire corpus of trash for any scraper willing to take it all in. You can then try querying AIs about some of the booby traps and see if it elicits a response - then you could even sue the company stealing content or publicly shame them.

There should be a federated system for blocking IP ranges that other server operators within a chain of trust have already identified as belonging to crawlers. A bit like fediseer.com, but possibly more decentralized.

(Here's another advantage of Markov chain maze generators like Nepenthes: Even when crawlers recognize that they have been served garbage and they delete it, one still has obtained highly reliable evidence that the requesting IPs are crawlers.)

Also, whenever one is only partially confident in a classification of an IP range as a crawler, instead of blocking it outright one can serve proof-of-works tasks (à la Anubis) with a complexity proportional to that confidence. This could also be useful in order to keep crawlers somewhat in the dark about whether they've been put on a blacklist.

OK but why is there a vagina in a petri dish

I'm pretty sure no one knows my blog and wiki exist, but it sure is popular, getting multiple hits per second 24/7 in a tangle of wiki articles I autogenerated to tell me trivia like whether the Great Fire of London started on a Sunday or Thursday.

What if we just fed TimeCube into the AI models. Surely that would turn them inside out in no time flat.
