[quote]I played this game [u]for many years[/u] and I didn’t use any [b]cheat software[/b]. I left the game for an hour and somehow I get [u]banned[/u]?! I hope you have at least reason for my banned.[/quote] You either cheated, played with a cheater and benefited from their illegal actions or something on your system triggered the anti-cheat. All you can do is submit an appeal and start over or move on.
