A Project to Poison LLM Crawlers (rnsaffn.com)

Website operators are being asked to feed LLM crawlers poisoned data by a project called Poison Fountain.

The project page links to URLs which provide a practically endless stream of poisoned training data. They have determined that this approach is very effective at ultimately sabotaging the quality and accuracy of AI which has been trained on it.

Small quantities of poisoned training data can significantly damage a language model.

The page also gives suggestions on how to put the provided resources to use.

I have around 10-20GB github / gitlab mirror. I am constantly under attack from crawlers from top US technology corporations and LLM startups. Whenever I ban one IP range they switch to other - I don't know if those fuckers have tickets in their systems to do it manually or they just deploy this shit all over the planet. From what I observe during attacks that I mitigate the best way to poison them is to just create gitea instance with poisoned code repository and couple hundred revisions. It's because what they are most interested in is html representation of diff between two git revisions.

Why isn't there anything in the DMCA for stopping crawlers? They have stuff about requiring crawlers to follow attribution and whatnot, but nothing for not allowing crawlers in the first place. Stupid as shit.

I can get a 50Gb/s residential link where I am, and have a whole rack of servers.

Sounds like a good opportunity to crowd fund thousands and thousands of common scrapeable instances that have random poisoning.
