I started spectating you when I saw you attacking a teammate who had accidentally hit you in the back.
A few minutes later a vanguard on your team hit you.; he was a level 0 noob. Instead of blocking him and using the voice commands to say no, you attacked him, fought him for 30 seconds and teamkilled him.
This is the third time I banned you for doing that and this time it's permanent.
I don't think you attack teammates for fun; I think you attack them when getting hit by them upsets your poor little ego.
