I don’t think so. Integrating with existing AI services equals direct privacy concerns to me.
A solution would be a self-hosted model, but then that could cost a lot in machine resources for instance owners, especially bigger instances.

Even then I’m having a hard time thinking of a useful usecase for an LLM integration on Lemmy (or even social media in general).

Browser fingerprinting is a thing (identifying someone by their browser’s configuration and fonts, amongst other things), but I don’t see them using that for bans honestly.

Absolutely, everyone is welcome :)
Enjoy your stay!
