Moderators and administrators can change warn status and the end result is (on most forums), your account is banned or disabled for X time in IPB. Though maybe F|A uses it as a trial judge system as you're still on trial.

Lol, in that case it's impossible he was cheating. I mean, when has PB ever let us down?! SLAC still won't detect everything.
To be fair a hacker is always a hacker. If you cheat, you did it for a reason, and you won't stop. It's either for e-penis or just because you're too competitive. Look at Tormentium for reference.
