I'm not supporting AI, but I still stand using AI isn't against forum rules except you can bring the proof where the moderator said using AI will get banned.
So far, if you leave a source of content, you will not be banned because you don't plagiarize anything.
But if you overdo with many zero-value posts by copy & paste from many websites or AI, you will get another problem and your account can be banned too. An account with many deleted posts can get a temporary ban by shit posting and getting four temporary bans will cause you a permanent ban.
I agree that AI-generated content can be abused by like you discussed here, a source can help to avoid plagiarism.
