You know all points bulletin?
It uses just punkbuster,strangely staff apb able to easily delete cheats.
I believe that their method of ban comes just in the local disk C:
I think they bannino the local disk, the reason for my assumption is that a month ago I deleted the C: drive and strangely I could play at all points bulletin
My question is: can unban the local disk without deleting it? Which factor is banned?

Thanks
