I've see https://xtremeidiots.gameme.com/playerinfo/381051 on your #2 push server a couple times over the last few days. He is fairly obvious in his use of a wall hack, as he'll prefire a wall before any sign of an opposing player. This, coupled with the fact that he has >200 hrs played and has progressed quickly up the ranks on your server is all good reason to at least check into him. His name changed, but always seem to have the nuclear symbol at both ends.
Appreciate you looking into it and thank you for providing the server!
