Racist group on League of Legends - where are you Riot?!

This is my copy of a post from EU boards because I think that everyone in this game deserves to know that under their noses something like this exist:

"OK, ok. I need sometime to calm down.

Just... Did you know, Riot, that there is a group in League of Legends, on EUNE, that is called "Ku Klux Klan White Power" ???!!

I mean... what the- This group and everyone in it should be permamently banned! I seriously think that it's wrong that it can even exist in this game while you are censoring so many words that we even don't understand why.

WHAT THE F?!

I was never a victim of racism but I'm so ashamed that people make this kind of jokes (is it a joke?). It's so immature, sad and pathetic that I can't even think about the reason why someone would create it. Humans are disgusting sometimes."
