No i did not have rebel license, and i didnt actually kill anyone. Me and a mate just fired a few shots in the air, then i talked to some people in the area, shot some buildings (which were empty). Me and my mate did encounter a guy who was sitting in a car in the street, and we talked to him a little. While we didnt mean any harm, he (the guy in the car) may have perceived it as threatening (We also suspect that guy was an admin, but we're not so sure)
While i do understand the concern, i think its a little extreme to get banned for doing a (nearly) harmless thing right before a server restart. I'm not saying it should be full-on anarchy when a server restart is about to occur, but it should be allowed to mess around a little bit, since there's no point of doing anything else
