In the times I have reported people in game for real problems (racial things and feeding, not dumb, angry speech), I have received maybe 2 messages that someone has been punished. Just, hey, the guy you reported recently has been punished.
You know what, I want more. I wanna see who, what, for how long, and a rating system asking for my satisfaction for what has been done. Name shaming is not allowed on the boards, but who does this protect, only the worst of players. A bad player won't be mentioned, not worth it, but someone who does things like feeding would, and that is what Riot bans, to protect them. I will vote with my wallet. I'm done with buying skins. I do not feel supported.
