Roy would not have been banned if he just said "kill yourself xnator", since that is a very minor breach of TOU (I still would have kicked him, however).
The issue lies in the fact that he refused to listen to staff, showed a shitty attitude and constantly left the channel when being spoken to. No matter what part of TOU he had broken, I would have moved him into a spacer to tell him what would happen if he kept breaking TOU, and we would have had the same outcome.

Also, Red, the reason people tend not to get punished for saying "kill yourself in GTA" is because Chute constantly uses the "in GTA" loophole, so it would be unfair for us to punish users for it (and also Chute would probably not allow it, since he says it). I personally would still punish for saying "kill yourself in GTA" if Chute did not constantly say it, because it is technically a loophole.
