OP, you are new, and you don’t know everything that happens on the forum. People use AI on the forum, and we will not be able to completely limit this, but the especially stupid ones do not bother to at least slightly correct the posts issued by the AI. Such posts are discovered by users, after which a complaint is received to the moderators for deletion. What you propose is quite fussy for development. Spammers on the forum are not allowed to exist for long, since sooner or later attention is paid to them. Not all short posts qualify as spam posts, and similarly, AI posts are not always short either. My opinion is this: if the forum does not approve of AI, then let’s not reinvent the wheel and use the old grandfather’s method: press the button and send a report. If this is difficult for you, then there are many others for which sending a report takes two or three seconds.

And yes, do not forget that AI is a machine, and it often makes mistakes, and you will then have to explain it to a person.
