Blizzard you need to bring down the hammer on toxic players immediately

I just played a game with a 4-man premade that blatantly used the n-word multiple times and they brag about using it without repercussion. I reported all of them after the game but I know nothing of true consequence is going to happen to them. It's the 21st century, this form of hate speech has zero place in our society. I'm not taking about safe spaces and political correctness, I'm talking about blatant racism.
