I've reported a couple of people for being toxic and I'm not really sure if it worked. This article says riot will inform me if they have taken action on my report, so far, nothing. Has anyone actually received a notification that the guy they reported got any form of punishment. I've been with toxic team mates, and I've seen them throw and curse someone even for smallest mistakes and yes I mute and report them, but I don't know if they really ever get punished.
