The first thing we should stop calling it Artificial Intelligence and more like Artificial Shitposting, cause in most of those cases there is nothing intelligent in it, just the same shitpost you would get for plagiarizing an article or using a word spinner on the previous right answer.
In my opinion, anyone caught doing such a thing should get a 7 days ban and then a full ban if caught doing it again, this is to give him time to defend himself in case of a mistake in detection, but overall we should discourage this as much as possible, it's bad for the forum it's bad for discussions, there is simply no positive thing coming out of allowing it.
you're gonna have to ban a looot of people
