Really, we don't know why he banned you the first or second time. You don't even know why he banned you.

Wait and see why he targeted you before we lynch the gm. This could be something all m-boxers could learn from, maybe an addon or software device to avoid in the future to keep from getting flagged. Who knows? The GM could be an m-boxer himself and the flagging be something unrelated to m-boxing.

Now, if this guy is just a hater, I've got my pitchfork ready and polished in the barn.
