I received two games bans on my steam account from my friend playing on it, one was for RUST which is fair enough since I let him use it for RUST, but I also got one for DayZ, I haven't played or touched DayZ in months and neither has my friend because ever since I've changed my information, any idea why I could've got a game ban for DayZ, I'm not too bothered about getting unbanned but I'm just curious why I did get banned.
