Hello Jody,
I'm sorry that you feel this way, but what you described about TheAaron doesn't really feel like his personality. Yes, what he seems to have done to you by shooting you down, is a tad bit unorthodox. Regarding the 'Teamkiller' named "Erip" have you ever made any complaint to an admin or said anything in the discord to alert any of the staff to what is going on?
Signed,
