I told you that you broke 3.4 by walking away from gunpoint, you had broken several rules, and showed no remorse for your actions. When I attempted to talk to you, you said you didn't care. Make a ban appeal if you wish to be unbanned.
Mate, I suggest you read the rules before playing. You say you have done nothing wrong and you broke 3.4 big time which suggests that you haven't read them or haven't read them properly. Use your ban to actually read the rules and get a hang of them, if you feel like you're ready sooner then make a ban appeal here. Also, be sure to follow the template when applying and make sure that you put a lot of thought into it, not just a 2 minute scribble, that is the mistake that most new banned players make, who of which are applying to be unbanned. Find the template here to save you some time.
