Even though video games are meant for fun and relaxation, some gaming communities have turned into something dark by becoming so toxic to the point where you wouldn't derive any joy being in any of them.

League of Legends is one of the worst of such toxic community. It was the reason why I couldn't keep up with playing the game. There's so much racist, profane, and inappropriate language used by players of the game which I can't stand.
