I agree with spindiggy. At the moment we are tracking some players that we know are cheating and have not been caught yet. Those were too cocky and exposed themselves on our server. This is why we also joined PBBans recently. We noticed some very unusual gameplay over the last 2/3 month and scores, kill/death ratios became unusual high in BF2142.
Also i noticed that normal gameplay comes back, however my "gut" feeling tells me that punkbuster discovered just a tip of the ice berg...
What happened about the idea that a guid ban was linked to the serial number of your cpu (and /or mac address) by the way?
kind regards, eric
