@BobCollins @mattblaze @Shatter242 It's a little different in the sense that they do it after you make one instance owner/user angry, as opposed to preemptively adding you to a list.

But there's two signs of this; you won't see posts on remote instances you make and you will find yourself staring at the "request sent" screen if you follow users. Some instances like FSE (funny because the name is a joke) prefer to null route IPs instead, which leads to the funny situation where as they've null routed this instance for some reason, it's blocked my home IP address from their instance. I was never told what set him off or made him block me for any reason, maybe it was joining an instance he hated.

It's all a false sense of security since if you're trying to protect users, people on instances you've blocked can see posts that get to their instance and yell things at you without you knowing.
