Yes... he was active a few days ago. Apparently there is some "super ignore" ( Block above member(s) totally) setting for users which you can set so you both cannot see a person's posts but the other person cannot see your posts. Unless they altered this now and only administrators can set this.
Its is a little fiddley to get it to actually work. I guess he did put a bunch of us on super ignore then..
I think he should not be banned when there's an ignore button where you can actually ignore him. There are many more people who might agree with him or want to read his messages. Banning him for saying something is not right. PS: I might not be aware of what he had said.
Maybe the owner of this site doesn't want it to become known on the internet as a haven for racial hate speech klans. 'Ignore' wouldn't prevent that label, and it probably wouldn't be good for business. IOW, I understand the ban. There's always Parler for you ... oh ... wait.
