So you ban him because you thought it was him?
That's a rediculous reason to ban someone with no proof. If your going to ban someone on hacking get a demo or it's useless. You can't just ban people because you don't want to lag any more either. If someone doesn't know how to fix there rates, show them or teach them. Not everyone is as smart about this game as you or knows how to get into there consol.
Don't ever give player shit if he's not doing anything wrong. That's just a way to begin a flame war.
