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 dont know where to post about wrong banned account in MW2 because of VAC , i read these news about these bans ,and valve can offer free Left 4 Dead 2 for those who had a ban for ,well lets say FOR NOTHING !!!!!! , i dont know that i or wee can post here to get the free Left 4 dead 2 , but i dont know how i would know that i can install or play it , so my nick name is " nikromants " if this keeps going whit this VAC , than i never will buy any game from VALVE ,maybe only some 1 game in year that is cool , but i dont think ;) that ,that day will come .

  • ppl listen closely its a computer mistake so dont be so pissed, i mean no one is perfect right? And, alot of you guys are complaining about hackers, and my answer to you is that hackers are hard to stop especially whit call of duty because the game is so freaking popular. i mean its the same in counter strike nearly everyone can hack in it. I have two friends who used to hack in counter strike and they never got banned. And they played the freaking game for like 2 years. they could hack because they allways was new hacks to find and new ways to hack. thats the proff that its very hard to stop the hacking from a game especially whit a computer game because its so easy to just download a file and use it.
    but if i should come up whit an idea to stop the hacking it would probaly be to have online staff that will response to reports, and then maybe a search a log book whit a video of every killcam in the game then when the player reports the hacker the staff can control the 3 past maps for hackers and the 1 after the report have been filed. Well thats what i would do if i owned the right to a big video game. but IW doesnt really have that kind of money in there pocket because of the financial crises we are in. i hope all of you will have som understanding for the IW and to those guys who got banned for not hacking i can understand you anger but dont be so hard on them, have mercy on them :D that was all i had to say. btw some says that there isnt hackers in teamfortress because of a better anti hack system but its only because who the hell wants to hack in teamfortress?!?!? :D

  • Ok you can make new maps, fix glitches, all quality conformance inspectiors are working even today on inwinity ward. HOW THE F*** YOU CANNOT CHANGE A HACKING PROTECTION? ALL WE KNOW VAC2 AIN'T DOING A SH*T ABOUT HACKERS, IT EVEN LOOKS LIKE ITS INGORING THEM! somebody might say "Ya dude when the game is out it critical files cannot be changed" BULL**** I BEEN SEEN CRAPPY FREE TO PLAY GAMES INCLUDING CROSSFIRE, WARROCK AND MEABY OTHERS CHANGED THE HACKING PROTECTION OVER 3 TIMES! SO HOW YOU CANT CHANGE IT? STEAM COULD JUST DELETE ALL THE MW2 FILES AND MAKE PLAYERS TO DOWNLOAD IT AGAIN... back to the banning.. HOW IT COULD EVEN BE POSSIBLE TO INNOCENT PEOPLE GETTING BANNED IF HACKERS AND GO TO SERVERS, PENERATE WITH THEIR AIMBOTS, MAKE THEM LOOK LIKE AN ASS AND STILL NO BAN EVEN MY STUPID GOD DAMN "FRIEND" HAVE BEEN REPORTED TO STEAM MORE THAN WH*RE GETS SHES P*SSY F**CKED IN YEAR. sorry for my adult containing comment but thats something i dont understand. Yes i have playstation 3 too and mw2 on it but i suck a$$ on it. I like more fps on pc, but unfortunately you cannot play it couse theres like million geniuses with aimbots, wh and other bullsh*t. Like theres no other game on valve what having that kind od issue, css vac pwns hackers, left 4 dead 1 & 2 no hackers at all, teamfortress! steam, valve, activision, inwinity ward! do something to same this game!
