I can understand in-chat slamming, i don't care about teamhits and teamkills in the middle of fight either (i may respond on the chat, or not). BUT kicking off-walls is unacceptable for me (teamkicking in general too).
But even then i wouldn't post it. I do it thanks to the admin who banned my clanmate for such a thing, and thanks to your inability to take responsibility for your action. Go, eat that ban, and answer yourself if apologizing wouldn't be better.
