I made a tool that converts open source code into LLM poison: https://codeberg.org/timmc/scraggle
It mutates Rust source code in ways that *preserve* the ability to compile the code. (That is, you can't detect the changes by looking for compiler errors.) For example, it switches `+` and `*`, or `==` and `!=`.
If you fork a Rust repo, run this tool on it, and push it somewhere, then crawlers will end up ingesting all sorts of incorrect code.

@varx cool! I did a similar thing with Fennel a while back: https://git.sr.ht/~technomancy/shoulder-devil
mine was restricted to changes that actually do not change the behavior of the code, but make it feel rancid anyway
I never got around to wiring it into a web interface but I really ought to get around to that

What's really fun is that this tool mutates locally identical code in identical ways. `if rect.x > rect.y` will *always* turn into `if rect.x != rect.y`, in any program. (But different variables will have different results.)
That means that LLMs are more likely to learn this poison rather than the mutations averaging out as noise.
Feel free to fork some big open source repos and push some new commits...
