if you didn't rdm, then you're rdm baiting lmfao.
Intentions cannot be proved from one person to another, but in this case, you're directly chasing him and punching towards him.
Did the other guy over react by pulling out a gun? Yes, but is that against the rules? No, he was justified to threaten you, he felt in danger. But for you to play the victim card of "I didn't do that" or "It's his fault" is just blatantly wrong.
I'm not staff anymore nor can I read your POs, nor do I even play the server, but the first sentence here summarizes this entire ban. 5 days is a little harsh, but you're clearly just looking for a reason to kill someone. This is a mafia server, not a pvp server, not every interaction needs to end in violence.
