Let's get some things straight and clear:
- you are NOT banned for playing badly (regardless of what your teammates claim)
- you ARE banned for ACTING badly towards the other people in the game
- what is most likely happening (since you're not posting your reform card, I will merely have to extrapolate the likely situation) is that your teammates are being not-so-nice to you, and you become a jerk to them in response
- Retaliation is NOT acceptable
- The ignore/mute function is there for a reason. Use it.
If people are being a jerk to you, that does NOT, I repeat, that does NOT make it acceptable for you to be a jerk to them. Ignore them, report them, and move on. It's a game.
