I see no information on this 10 post thread that they are "banning Linux players". I just see a few people saying they weren't cheating who got banned.
A little Occam's razor here implies it's just a few people who got caught cheating and won't admit it.
It could be either. It's not at all far-fetched that the anti-cheat looks at it's environment and realizes that things ARE NOT normal - different tricks and layers are used to make the game run at all.
Then again you could certainly be right, and it's just a few cheaters crying trying to cause a fuss to get unbanned.
As the original admin for the Steam forums at launch and an active participant there for years, I have seen my share of "
I'm innocent!" cheater posts. That's a lot of the basis of my opinion on this.
