I was reading on PBban that PunkBuster can ban a complete Hardware/computer so that this particular pc will not be able to play any games related to PB.
here is a small excert from
Is this true?. I kind of find it hard to believe since most user here just buy another cd key and restart all over.PunkBuster(TM) now computes Hardware GUIDs for various pieces of hardware on players systems while playing on PunkBuster(TM) servers. When players raise a violation that corresponds to hacking or interfering with PunkBuster(TM) normal operation, we now (in addition to Global PB GUID bans) are Globally banning the new Hardware GUIDs across all games supported by PunkBuster(TM) (including games supported in the future).
But could this really happened?
