Welll, have read through this and the rest and at this point MC needs to be banned, regardless of fixing the chat window. There are lines you do not cross and he has stepped over them. MC is no longer funny. If he has a sock then, he will be treated in exactly the same way as we deal with other socks. On a case by case basis.
As for never banning and always sticking them in Room 101, the answer to that is simply bwhitman. I don't remember the same outcry when he was shown the door.
