I have reported him already and you did give him a warning to shut the fuck up! He really is not caring about it! He is still spamming chats, rendering the chat section useless for the rest of the players. Racist remarks and comments like 'Autistic team'... well... that's a different story!
If the chat spam is just for a few minutes, it's acceptable! But he is doing this for the whole round!
How would you feel if, for an entire round, the chat looked like these screenshots?

This is worse than chat spam! Please warn him or for the better ban him. Or if it is possible, please for the sake of everyone, mute him!
