Typically, if you see that one person is being banned from a bunch of communities at the same time, it just means that they are being banned from the instance.
If an admin wants to ban one of their own users, it’s a single activity that’s federated out, but if they want to ban a remote user, the only way it can be done under the current system is for every community that the banned person has interacted with to ban them. It’s an automatic process, triggered by the admin pressing one button once. (it’s not a perfect solution, because nothing prevents the banned user interacting with other communities, at least as far as their local instance is concerned).
That’s not quite correct. An instance ban works just fine without corresponding community bans. What didn’t work, was content removal. An instance ban issued with removal of all content posted by a user used to just remove content locally without federating the removal.
To get around it, instance bans now issue community bans too, so that content removal federates. However they still create community bans it even when content removal isn’t selected during the instance ban.
