Earlier this week, there were reports that large numbers of Modern Warfare 2
players on Steam were getting erroneously banned by Valve's Anti-Cheat software
. While such claims are usually best taken with a grain of salt, the quantity and suddenness caused speculation that Valve's software wasn't operating correctly
. A few days later, Valve president Gabe Newell sent out an email
acknowledging that roughly 12,000 players had been inappropriately banned over the preceding two weeks
. "The problem was that Steam would fail a signature check between the disk version of a DLL and a latent memory version. This was caused by a combination of conditions occurring while Steam was updating the disk image of a game." Valve reversed the bans and gave free copies of Left 4 Dead 2
to everyone who was affected.
