I have no proof because I assumed that because of the amount of pissing and moaning Kalphiter does over TF2 he'd come up with some bullstuff logic about how "poorly designed" TF2 is justifying his use of hacks instead of actually denying the whole thing
Off hand the only people I can remember who were on the server at the time were Dracpot/DracoSoul and Sue/Dusty12, but there were at least 4 others
Doesn't the server have chatlogs or something? Because I'm pretty sure he said something about how surprising he thought it was that the speedhacks weren't "patched", and before that he was talking about how he uses aimbots
