It's that you contradict yourself. If you did not care what people thought of you then technically you would not be here questioning the existence of this thread, you would accept it and ideally not be bothered to reply to it. That would be "not caring". That is also the purpose of the "ban if you post about not caring" rule, to weed out bbrown town self contradictory Look-at-me! posts.
But you come back for more, you obviously do care.
