Haven't seen this anywhere else, so figured I'd post it. It seems that not all games that use PB actively check to see if it's running, so you can kill the process after launching the game and you don't get kicked. Not sure if this will actually stop any bans, but if you're paranoid you might as well give it a try.
KillPB.bat
Make sure you run as admin to have permission to stop services and protected processes.
KillPB.bat
Code:
@ECHO off
sc stop PnkBstrA
sc stop PnkBstrB
taskkill /F /IM PnkBstrA.exe
taskkill /F /IM PnkBstrB.exe
exit
