3+ days ago a player on my team made fun of the holocaust and jews, and is still playing today

About 3+ days ago, I played an ARAM game where our Ezreal said "mmm crispy jews" in all chat at the start of the game. I reported him after the game, since that deserves a permanent ban, yet I just checked his op.gg and he is still playing the game on that account. His last game was 2 hours ago. Riot?
