I've been thinking lately about AI poisoning. I want to make this post a thread for suggestions about which tools we can use to fight back. Bear in mind that I'm only talking about poisoning tools, not blocklists or bot-detection utilities. Here's a short list of what I have so far:

Website protection tarpits for text poisoning (fighting web scrapers):

  • Nepenthes was one of the first. In the words of its author, "I’m just fed up, and you know what? Let’s fight back, even if it’s not successful. Be indigestible. Grow spikes." Nepenthes's demo page is here.
  • Iocaine is the best tarpit I know of right now. It's very well-designed and performant. Version 3.0x is complete, and the fourth version is a work in progress. It's made by Gergely Nagy, who goes by the pseudonym "algernon", after the character by the same name from Flowers for Algernon, by Daniel Keyes. Iocaine's demo page is here.

FWIW, while iocaine does generate copious amounts of garbage, it is never going to poison LLM training data: it's trivial to filter iocaine-generated garbage out pre-training. The garbage is there for two reasons:

  1. To serve the crawlers something.
  2. To poison the crawling queue.

Not the models, the crawling queue. Place an identifiable substring into every generated URL, and you can catch any crawler that works off of a queue collected by cheaper crawlers.

It's not really a poisoning tool - it originally started with that goal, but that goal has changed a loooong time ago -, it's more bot detection & mitigation nowadays, the garbage is just one of the tools it achieves this goal with.

But while I'm here, I'd like to mention Alun Jones' fakejpeg (or my rust port): a library that can help you generate structurally legit-ish JPEGs, files that most decoders will happily display, but with entirely random content. Generating them is very cheap. How effective it is in poisoning? I don't know. But I find great delight in looking at the random noise.

AI, in this case, refers to LLMs, GPT technology, and anything listed as "AI" meant to increase market valuations.
