Yeah two hours total time and 45/5 after 10 minutes. I put the ban on, but I don't have an IP, so if he has another account (which I assume he does), then he'll still be able to get on.
 
He's a hacker, but I don't have 100% proof, so I'm not tossin' it in there.
 
I think it is reasonable to assume he was aimbotting. He only played for 10 minutes and thus had 4.5 KPM and 86% headshots.
