Toxic players

Hello, is there a way to report toxic players to ban them from the game forever? Since the game is hard, and there are always new players (or those who just give their maximum, but don't have skills), it pisses me off when I see someone trash talking their own teammates, saying things like: "you f* idiots", or a team trash talking the enemy team. Unfortunately, I forgot the name of those that I played with today. But it's on EU server, and one of them is Shiro. Thank you in advance.

Very nice. You are here making up excuses to get people banned or at least telling a one sided story. A true OK-hand sign. Mute them. Some people play really badly it is a fact. I myself have seen people who move like bots and it really is hard to watch.
