PM him:
Tell him he has a certain amount of time left before we get him permanently excused from anything ToriKnight related, and close that Social Group. He could get banned for this kind of thing, or face a even less severe punishment.
PM a Smod:
Tell them he is a fraud ToriKnight member, and made a very useless Social Group, related to the clan ToriKnights, and tell the Smod to delete the Social Group. Ask the Super Moderator if this kind of thing is a ban offense, or something to get him warned and/or punished.
I'm talking to Ofillusion and Warmedic, since the other members of the lesser importance of the clan, and you guys are the leaders.
