Sigh...

iScending: OP, I'm sorry you were banned, but as the old saying goes:   Don't do the crime if you can't do the time   You broke the rules. You team killed. There is never an excuse for doing it. 
We changed the parameters for the system in the last patch and it is now much stricter (as you may have noticed) and as a result more players will find themselves banned. Hopefully this will lead to less team killing since it's not something that we tolerate.
