Do they enforce it? Some of their biggest writers do this regularly. They don’t always name names but if I can tell who they’re talking about, can’t Medium?
I’m unapologetic when it comes to blocking jerks. I too was attacked Christmas Eve—by a “Christian” who called me a slew of nasty names after I gently pointed out her hypocrisy for seriously libeling (as “murderous drunks”) members of a different religion. I wouldn’t have bothered reporting her attacks but she also called me a “snitch” I couple of times so I figured since she already thought that, I’d go ahead and prove her right. ;)
