Though I lack solid proof, I was part of these matches and can only comment on what I saw and the teamhits I felt. To put it bluntly, your post is BS. The door opening went on all through the night until your ban, then stopped. Odd. Teamhits? Only one guy? I'm one guy, a few clanmates were hit too and complained over vent.
Anyways, back on something that can be seen as proof. If you opened doors once, and teamhit once, I doubt the entire team noticed. Now I do understand people hit 1 just to mess with people, but a majority is a majority. If you gained more than half the servers attention, clearly you did something stupid multiple times.
