thats why I have 4 Accounts on 2 Machines witch 4 individual Steam-Numbers. No ban for me. And for VC, I was baned 15 Times now, I allways use same name and Game, cause they ban the ID.
Best Anticheat ever is CD = Cheating Death, for CS 1.6 but there are still Programs that run in the Background and still can be used.
Enemy-Detector for older Game-Engines like CS is are the perfect hack, and undetected since 3 Years.
There is no Anticheat the really can stop Cheats, just better skill
