Valve Apologises for Wrongful Modern Warfare 2 Bans

By Alice O'Connor, Jul 27, 2010 7:10am PDT

Steam proprietor Valve Software has apologised after its cheat-detection software banned over twelve thousand innocent Call of Duty: Modern Warfare 2 players.

Non-cheating gamers were flagged as cheaters by a mistake with the Valve Anti-Cheat feature of Valve's Steamworks suite, which Modern Warfare 2 uses. "The problem was that Steam would fail a signature check between the disk version of a DLL and a latent memory version," Valve president Gabe Newell wrote in an e-mail to the victims.

"This was caused by a combination of conditions occurring while Steam was updating the disk image of a game. This wasn't a game-specific mistake," he explained. "Steam allows us to manage and reverse these erroneous bans (about 12,000 erroneous bans over two weeks)."

"This was our mistake, and I apologize for any frustration or angst it may have caused you," wrote Newell. Valve has granted those mistakenly banned a free copy of Left 4 Dead 2 to gift to a chum plus a free copy for themselves if they didn't already own it.

Thanks to the many, many people who sent in tips on the subject.

  • I too have been playing alot of modded ground war servers lately where a ton of random shit is happening. Tonight i had tried to log on while also connected to a skype call. I thought at first it was because i was on skype, my friend being like "ya, that could be cheating because you could ghost so easily". So i turned it off. The problem still persist, it kicks me out of multiplayer screen and opens a second window saying "cheat detected" ive run my virus scan, scandisk, checked for spyware, closed all open ports, even rolled my computer back to a previous checkpoint. Im failing to see how something is being detected when nothing is running in the background other then nessecary windows files/programs. Then i came across this post and ive been exploring google threads saying that VAC is responsible for this happening to thousands of people. Any help on how to solve the problem?

  • i was playing Mw2 1 night then i got into this server and i didnt know that it was a hacked server until i saw people FREAKING jumping up so high..then when i killed a person i unlocked every single titles, emblems, ..etc i was like WTF?!

    the next day i played Mw2...i cant open my COD mutiplyer then a small window pops up saying "Cheat Detected" and i saw on my VAC status i was banned coz of hacking WTF is that?!

    i dont know if VAC is just FREAKING dumb or theres something wrong with it...i've been playing 507 hours online and that VAC will ban me bcoz i got into this hacked server?! FUCK IT

  • This time, they hacked the hell out of MW2 BIG TIME, now real hackers are having hosted games that you will "join automatically" AND YOU CANT DO NOTHING ABOUT IT,

    Modded games like, your gonna be flying lol,, you cant choose your weapon class!! unlimitted ammo!!! and shit like that!!!,,

    Now the problem is,, if valve and steam and their useless VAC crap banned people by mistake for nothing and I was one of them btw,, what makes them NOT ban them again for just joining a hacker hosted game!!! I mean its not like they wanted to join them!! they were sent there! lol,,

    Sad huh?! lol,, but am really happy tho,, its good to see valve suffer the consequences of their stupidity.

  • So like a month or two ago. i was banned. i brought it up with the help function in steam because you know steam doesnt have a phonenumber... little shady? anyways they say the ban is legit and i was hacking. although they wouldnt tell me when "they found out" or the time the ban was issued or hacks used. so even more shady.. modernwarfare is still 60 bucks when it should be around 50 there keeping it at that because banned people buy the game again so tehy continue to make loads of cash on wrongfully/rightfully banned people. whether or not they say they care and want you to have a good gameplay they dont, in it for the money. as reading on here many cases people were banned even after they made a 2nd account for no reason etc etc.

    Steam/valve whatever is a really shady 3rd party program if im correct in calling it that. they take your game that you bought and limit it to one account... so dont buy stuff on steam buy it in person at gamestop etc.

    I know this isnt going to happen... but come on gamers lets go on strike we can beat steam the money grubbing, shady thieves selfish cockadoodledoo's.

    the point f this post is to stay away from buying stuff on steam get it retail and try to stay away from buying steam games.

Any ways please respond to this with any information you have as to how i can contact someone who cares and will listen so i can get this fixed.
