Does Riot really care about toxic players?

So basically I encounter many toxic players. they talked crap and acted like they are real challenger player even though they are silver are even worse. They call people by name, call them trash, idiot, r%%%%%ed, etc. I did report them eventually but they did not get banned or any penalty. so does Riot really care about? Plus, sometimes we lose a ranked game just because of 1 single troll-er, if they do get banned, should we get the lost point back? it's not fair to lose points because of someone who is literally trolling.
