You should submit a support ticket to the Even Balance (PB Developers)
http://www.evenbalance.com/troubleticket/new_ticket.php
Include all running processes etc that are running at the time you're kicked.
If the demos show clear evidence then send them to clownbase, but since clownbase is supported by GV and they don't ban demos all you'll get is a CB ban. That is useless as well since the cheaters will just change GUID's and rejoin.
@Kolor - Those boxes in the SS are a toggle (light grid) in Cbopat's demo player clickme
If the server it was recorded on was streaming here at the time then send it to the server owner for them to submit here. If no stream then there's nothing you can do with it. you can check the server to see if streams on the main page - http://www.pbbans.com/ (under donation button on the left side)
