Did Riot eventually sort out the toxic community? If so that would be amazing, and definitely relevant. I stopped playing when it was still there, and it was a big part of the reason I stopped.
I’ve been playing very very active from 2010 to 2014 and since then on-off, sometimes skipping a season.
Recently picked it up again and I noticed that I didn’t had to use /mute all anymore. I’ve got all-chat disabled by default so I’ve got no experience there, but overall I’d say it has come a long way.
But I’d also say it depends which mode and MMR you are in. I mostly play draft pick normals or ARAMs in which I both have a lot of games played - I heard from a mate that chat is unbearable in low level games.
The only success I've seen in sorting out random vitriol is cutting chat off entirely and minimizing methods of passive aggressive communication. But Nintendo's online services haven't exactly scaled to the typical MOBA size to see how it actually works out
