Isn't this guy a jerk and a bully? How to deal with this person?

Hi everyone, so I've been chatting with a guy from this site for quite a while. In the beginning he used to be nice and I liked talking to him, but he hasn't shown his true colors yet.

He said some pretty f**ked up stuff. Not only the guy was racist and islamophobic (he said that people with darker and Arabs skin color are trash), he was also mean, demanding and a bully..
He constantly demanded to answer to his messages every 5 minutes and asked for my personal answer; when I had the nerve to disagree with him and didn't do what he wanted, he started calling me names like loser, boring, fat, short, ugly.
He eventually blocked me, but a friend told me that he's still badmouthing to people on the site and spreading fake rumors about me...

What should I do? I've never met such an evil person in my life
