Teh Evil Traffic Cone's ID is 12375
The others connected to his server at the moment are Sherwood (18721) and two clients of Magician (21535). Both of these other users have super admin.
I checked for an obvious impersonation attempt and searched The Evil Traffic Cone. Only result was ID 5702 back in 2010 alongside several other impersonation attempts by 5702, who was last seen in 2011, so nothing there. Still, I could swear I've seen "Teh Evil Traffic Cone" drama'd before, or was at least being a douche on some other server.
Still, OP, next time use Shift P to take a HUD screenshot of chat (I think it's Shift P, check your controls section just to be safe).
