To prove how flawed Battlefield 3 anti-cheat and monitoring systems are, hackers have used a PunkBuster exploit to ban more than 150 law-abiding players.
Cheat and hack forum ArtificialAiming instigated the bans and provided proof of their coup in a post (via Battlefield 3 blog)
ArtificialAiming's argument is with GGC and PBBans. These are third-party services that run on Battlefield 3 servers and provide a host of anti-cheat tools - live ban lists among them. GGC and PBBans were working together, but broke off their partnership in October.
"We are bringing back the unerring of PunkBuster back for a third season," read the post on the ArtificialAiming forum. "We have selected GGC-stream as the target since they have the most streaming BF3 servers and makes it very easy to add fake bans.
"In 2011 we hit them with a mass ban-wave, and now we are banning real players from Battlelog while GGC-stream is totally unaware. We have framed 150-plus BF3 players alone."
GGC-stream apparently denied the appeal of players who were framed by saying the bans were "legit".
ArtificialAiming even created a host of fake nicknames on the banned accounts to signpost the problem. Examples of these are "No_one_is_safe", "You_will_never_find_all_the_fake_bans", "BF3_fake_ban_#111", "GGC_is_not_safe", "Many_more_fake_bans_are_coming" and "This_is_a_fake_ban". And that was just for one banned BF3 account.
ArtificialAiming claims to have banned eSports League admins as well - although these bans were "quickly removed" by GGC.
"Thx to the GGC-stream team for the lulz," the post concluded.
EA and DICE are yet to comment on the issue.
