hedwards: Do you have any evidence to support the belief that it doesn't happen?
Because, I find it incredibly hard to believe that Valve is perfect and never, ever makes a mistake with their software. The quote itself indicates that Valve knows there's a problem with their software, if they're having to undo that many mistaken VAC autobans, what makes you think that they don't miss a few of them?
But, I'm sure it's easier to go with OMG teh horr0r sumbody h8 steem, than it is to admit that people do lose access to the only servers due to Valve's software not working correctly and unless Valve admits that there's a mistake, which they may well not do, you're in a situation where the account is not in good standing with little recourse.
Isn't that a silly thing to say? Really? Prove that they aren't banning people for no reason? How the fuck am I supposed to know? I've been a part of Steam since 2003 (when CS 1.6 was released) and I know lots of people who were banned. It then turned out that they were banned for cheating. There's only so much information that you can get from forum posts, and they are always simply one side of the story.
And no, I do not think that Valve are perfect. Far from it really. I find their 'customer support' abysmal. I hate their regional pricing. I hate their almost-always-online DRM. I hate their neglect for older games (i.e. CS 1.6) and I hate them for the useless VAC.
But this doesn't stop me from being rational. If you've got a quarrel about Valve, try to make it more rational than "Tell that to the many thousands of people that were banned by VAC due to a bug." Is that really representative of the situation? You come off no better as the generic moronic Steam hater.
