There's some great tips in https://support.chess.com/customer/en/portal/articles/1444877-what-should-i-do-if-another-member-is-rude-or-abusive-, including instructions on how to block particular players.
Ultimately, if you'd like to report the abuse, you can do so through Help -> Contact or https://support.chess.com/customer/portal/emails/new - when reporting abuse, please don't delete the message or user note, as the Support team will do this when they pick up your ticket, and you don't need to verify the abuse. If the abuse has happened in Live Chess chat, please get a screen shot as well.
Please don't reproduce the abuse here in the forums, as we don't need to give that sort of language any further promotion.
Thanks,

I have been a member of chess.com for a while now, and while some people gets mad over playing the game and so I generally don´t bother to pay attention to them but this member is sending the kind of messages that I find terrible
Is there a way to block him or I just have to ignore him.
Thank you
