I unbanned and dewarned both of them. You ignored some people without reason, and you solo played. I believe they were scared you might ruin game further after that ignore.
We advise people to use ignore against other players who insult and flame and there were none in this game. Maybe the kick wasn't justified and it's nearly impossible to tell without actually being present in game. And to make it clear none of the unbanned people are my friends.
You can be mad at me about unbanning them or you can ask yourself why your entire team wanted to kick you (and win game without you)
They kicked you because of your behavior, and if you behaved like a normal person I wouldn't unban or dewarn any of them, it's your behavior that made me do so.
