Does reporting somebody actually do something?

So over the last two weeks I have had at least 5 different player who were either extremely toxic were rage quiting or intentionally feeding. I always used to get feedback on my report like "One of your recent reports has been punished, thanks for helping to make this a better comminuty." Or something like that. But lately I haven't received any of those messages while these players were 100% guilty and are the part of the reason why I hardly play this game anymore. I still find it amazing how so little is done about these players who keep ruining games for everyone. Are reports actually registered does RIOT do anything with them? I feel a lot of players don't think this is the case and just don't bother reporting. Riot could you give us some feedback?
