What counts as being toxic?
I've seen recently in my humble Silver games how people respond to any slight comment on gameplay as being toxic. I'm new to league of legends (March 2017) and I know what experienced last year in terms of toxicity. From people telling other people to commit suicide in very creative ways to people commenting on others' mothers and how they had sex with them or intend to. But recently I've noticed that any slight comment on any gameplay is met with a harsh response like "Report this guy he's so toxic". What really makes me sad out of all of this is how Riot encourages this. I've stopped using chat for about a month now and I've decided to "/mute all" in all my games. Nothing changes because the post-game lobby still gives people an audience and I still see a lot of rubbish said all the time.
People don't know what it means to be toxic and deem any player who comments on their gameplay as being toxic or salty or something. This is my own personal experience and it could be entirely different for anyone else.
