How is this player not punished?

He said "go kill urself" 2 games in a row. The first time he said it to his teammate after game. The second game he said it in lobby to me. He said "bastardd" "go kill urself" "the world would be a better place without you". I reported this guy both games and i didn't get instant feedback report. Can i say these things and not get banned or is "urself" not equal to "yourself"??? I know riot doesn't approve of homophobia, sexual harassment and suicide so why didn't this player get punished?
