There is iocaine and nepenthes. You can easily deploy on your server. Given the scraper uses the correct User-Agent... which they probably do not do especially if everyone started deployed tarpits.

Would be fun if lemmy or piefed had an option to have the content of posts poisend as there are some new Crawlers crawling in the fedispace recently.

Or we could of course invent our own lemmy speech that is still english, but really weird.

Most of these (nightshade etc) are just a secondary form of AI grift that also doesn't work.

At best they last till they get effective enough for work arounds to be worth looking for, and then they're gone. The only remedies that stand a chance of lasting are legal.

You can target the crawlers using tar pits and proof-of-work application firewalls but I am doubtful that poisoning does anything. The second a poisoning method becomes common enough to have an effect the AI companies will just start filtering for that. Unfortunately the only way I see that prevents your work from being stolen is to either not publish it at all, or to only publish to smaller invite based communities that closely monitor who is accepted.

These things don’t work and are often just scam services sold to fearful content creators

A simple engine that provides grammatically correct sentences with random content, triggered by following links that are not user accessible. That's what we need basically everwhere.

That dude here on Lemmy that uses thorns instead of "th" has a pretty decent idea.

Add random profanity? Fuck.
