So essentially:
You made a ticket requesting a suit model on a civ char, after that ticket was made I sent a message in staff chat saying to appropriate your name once the ticket was addressed; it was maybe within minutes that I was told you were being argumentative about the name change request so I stepped in myself by pulling you into a sit with the original staff member taking the ticket being Augustus. When being asked about the name instead of seeing reason you just said "The server allowed me to set this name!" assuming that just because there wasn't a character limit that it would be allowed. I told you to change your name and you then pasted yet another long name in chat showing no intent to display yourself in even a somewhat serious manner and when I informed you that I had no other decision other than to ban you considering your previous infractions you began lashing out.
TLDR: You were asked to get a name change, refuse, asked by UA, refuse again and then proceeded to supply yet another stupidly long name.
You have been banned 3 times before this, two separate times for 1 month, one for 2 weeks, and have 4 notes on your account. Among these infractions are multiple offenses for metagaming, lying to staff, and one just being for flat out racism? With someone who has the record of lying to staff and having a complete lack of control over yourself I really feel almost no sympathy for this situation but rather for the fact that you actually need to find something else to do with your free time.
Your appeal will be Accepted but upon your next infraction you will be banned for 3 months.
