Sounds like something we had about 2 year ago too in DD2
someone with speed hack, aim,wh almost everything, and that name changing script
but if you really wanna ban him, you should put all players in to the spec, if they dont they'll be banned too (unban request =instand unban ofc)
and than just ban the team he is in

about those admins...
I think R4h doesn't even care if there are cheaters online
idk about Embrace
