What would have happened if he simply changed his ways, stopped using the AI bot and instead contributed positively to the forum?
If someone does not have the capability to write something on their own, how they will do that? Sometimes people have capability but they do it just because of their laziness. The main problem is everyone wants to make easy money (That includes me as well). But the point is, whatever method you choose, that should be ethical and legitimate.
One thing seems possible is that the OP would probably have escaped some (if not all) of the negative and/or neutral tags. In the interim from the first neutral to the first negative tag, if he had been serious about his remorse he would have handled this thread in a different manner.
As I said, probably he did not notice the neutral tags because maybe he has multiple accounts. Multiple account holders barely have time to check their account status. All they do is log in, post, log out, and then log in to another account.
