I don't know exactly how the system works, but I got a lot of warnings from matches I played.
I always get trolly little ****ers, sometimes a whole premade group of trolls, who bash on the whole team. And I always do my best to keep everyone positive and focused.
But if for some reason these guys/guy want to pick on me, they tell the enemy team where I am, what I'm doing, and it just really get's annoying.
So I just get to the point where I mute everyone. Keep in mind I never cuss out anyone, bash on anyone, or do anything negative, I just stay neutral, and every time, these trolls report for some stupid thing I never did. I always get that dang message after a game, and once I even got banned for two days because of these stupid trolls I always get matched with.
The system is so screwed up.
