Using AI to write on forum removes the originality that a forum is meant to have, and if it permitted, it will make discussions in forum sound very inorganic. You don't have to be under the pressure of trying to impress when you write on the forum, because that is when you can be tempted to want to do extra and use AI. It is bad, and is not a pattern that should be encouraged.

Since we are discussing AI, let me think out loud! what are the chances that if the same AI tool write on a topic asked by two users, what are the chances to provide the two users two different write ups on the same exact topic?
