This dude, is banned two times for wallhack, by @dertom and @Kurosaki . But he changes his keycode and comes back. He doesn't change key after he gets a ban, he changes the key like, every day he gets on.
After i banned him, i was gonna make IP Ban request, but i forgot for it. I banned him for now too: 3xP' Statistics ~ « Player Details
But he will be back later today, or tomorrow. Of course If he doesn't get IP ban.
