So I'm not sure if I'm actually supposed to do this or not, but I just played with a GP named Chalisar, who called the entire team a bunch of N****** the majority of the game, the rest was using his ult to give away our positions, selling his items to fill our base with wards, then after asking him to basically stop, he decides to keep filling our chat log with offensive language and refusing to surrender. So I hear about people getting banned for potentially a bad game (feeding). If I ever see this guy online in a game again, I will have lost all faith in this tribunal system. Offensive language, assisting enemy team, AFK, Verbal abuse.... Get rid of this joker.

Calling players out on the forums is considered bad form, no matter the crimes.

Also posting here will not increase the chances of his ban in any way.

Calling out players isn't just bad form, it can lead to a forum ban.

As for the case, he just needs a few reports then we can take care of him. If your team (and possibly the enemy team) don't report him, then we can't do a thing about it.
