Banning AI created content is a fine thing but banning AI translations can be a hurdle for non native speakers. For example I don't speak/write Spanish very well but want to reply in Spanish when the post also is written in Spanish. I use AI (deepl) for the translation, like I do in some of my posts. Nevertheless the replies and posts are written by me. Originally in German, then translated. Punishing that seems a bit hard to me.
