PunkBuster banning people Anonymously or just send the data on suspicious hacker to FF or BE. They're looking into it and banning or not banning the player.
Mostly PunkBuster just kicking from the game and locking for several minutes (that's what it did to me in different game).

But I've never heard of people got banned by PB.

P.S. Next time, ask questions in different section or just open a new thread by yourself.
