You had to mention his name at the registration, also something weird about this guy, he has same ping as modeler exactly, so if he will play he has to record his game fully.
Except for ping have you got proofs saying thats modelerv2? because it's bullshit from your side
EDIT: Btw, he can't fraps because ac is giving him fps drops, ask him to give you teamviewer and i think this would be good enough to prove he's clean
