I think that they pretty much decided what to do in those cases. Tricky part is to prove that someone actually used chatbot, but if you manage to do that I don't think that mods/admins will hesitate too much.
Yeah it is tricky, but we already found several tools that can help us to identify how likely is that some posts are generated by AI, and if they all show high percentage than case is closed.
However, I would not be so easy on banning every member for this before double checking, discussing with other members and hearing what others have to say.
Anyone who was suspected of using AI post generation multiple times should be punished somehow, maybe temp ban first instead of permaban would be better.
btw does anyone know how AI text generation is working for languages other than English?
