Even the Webgl signature check is resilient, and is the new tracking cookie on many sites like YT etc. It is a robust unique property of a specific system, and GPU. Not just the serial number... Indeed, duplicate salted-hash signatures on multiple active users mean shills, and immediate bans issued for both accounts tainted by the black list. The trick is to randomize a mix of easy and difficult signature checks daily. i.e. the exploit writers will have to spend time cleaning up bugs, redistributing the patches, and dealing with angry people that have a GPU that is on the blacklist for a game. The more hardware details collected, the more difficult it is to prevent tripping the admin alert. This is already done by some studios... "Play Stupid Games, Win Stupid Prizes" as they say... =3
