Steam will ban all of your games in your account if you play at a gaming Center.
I was playing at a local gaming center and they banned the two accounts I had used to login, over $5k in games banned just because I was playing at the local gaming center. When I asked why they said because it's the rule and then pointed me to some bs fine print on their website. I will never use steam/valve again. It's really sad that you all went with them because if you do a quick look they have done this to thousands of people. They are just a bunch of greedy (BLEEPS)
