Does Riot take racism seriously?

1/7/18 : During the match lobby this player decided to not only tell my friend and I to kill ourselves in a bathtub, he also proceeded to spam (copy and paste) the N word. And then when we said to stop or we would report he then told us he was related to a staff member and that doing so would not result in a ban. We muted him in-game and then reported him after the match ended.

I've gone through many staff members who have all told me to keep reporting any other players that do the same. Which at first I said okay and moved on playing the game, but I do check his account through the website and for some odd reason he is still playing games and is in full control of his account.

1/12/18 : I was in a live chat with the staff member, "Mr. Feeny", who told me this. "So the proper escalation of punishment is as follows 10-game chat restriction > 25-game chat restriction > 2-week suspension > Permanent suspension" "You can skip to a 2-week suspension for using racial slurs, hate speech, or wishing harm upon others." "Otherwise, you will generally have chat restrictions until reaching that point"

Which to me didn't really add up since my claim against this player was for the main reason of being extremely racist and blatant about it.

I would like some real answers and would like to not be told that they will "look into it". Because considering the player did claim to be related to a staff member and that he would not be banned for racial slurs and to this day has not had any type of punishment seems VERY fishy.
