Sir, please read the OP, besides you are not in a position to dictate what constitutes a ban. Amigo 😉
What you are saying makes no sense. So let's just assume a hypothetical situation. If a person makes a post just to troll, and it takes people lots of time to research on it and get back. Wouldn't that person deserve a ban?
There is no room for ambiguity here, you would get banned on every freelance site on the world.
