This is your 3rd ban, you've been banned once before for sexual conduct and another time without a reason. Typically when people get banned 3 times they will get a permanent ban, but considering you haven't been banned since July 2015 we only issued a 12 hour.
You need to control yourself, if you cannot due this then let us know. There are a bunch of ways to get a hold of staff, or take screenshots or video of people to get them reported and fix the problem. When you lash out on the server, no one looks bad except for you..
If you choose to rejoin, we gladly welcome you back but know that you need to control yourself in order to keep everyone else on the server controlled. If you choose to not come back, well.. I guess it's your choice but we did nothing wrong except stop a problem from escalating into something more severe. If you do this in real life, it will be very difficult.. just giving up like that. That would never fly for a job, school. If you just "walk out" you never get paid, or if you "drop out" you wont learn the things needed to survive in society.
Screwing up and getting disciplined is not necessarily a bad thing, think if someone else was doing this on the server.. would you want it stopped or the user banned? It's only 12 hours, I think they was extremely fair and that the admin did his job perfectly.
Don't let this ruin your game, it is in fact... only a game.
