How do Fediverse instance wide bans work? (self.fediverse)

I’ve not been banned myself, I’m just curious.

Is it akin to getting banned from every community on the instance, but the users profile is still visible from accounts on that instance?

Or is it akin to the user getting entirely “defederated” from the instance they were banned from?

It’s almost like their new posts are “defederated” from my home instance.

That part is odd and I don't really have a good guess or assumption as to why that's happening.

The posts they make are in a federated community with my home instance. I’d bet if they replied to this comment, I wouldn’t see their reply. (assuming this comment is even visible to them).

As far as I understand the system; banned users shouldn't be able to make comments on a home instance their banned from unless something is broken or has been deliberately been changed.

What I mean is I can’t see any of their posts they’ve made in a shitjustworks instance since their ban from my instance, even though my instance is federated with shitjustworks

I did get that, I just don't understand as to why that's happening; maybe a federation error?

All I know is that instance defederation on lemmy has a similar error. Sometimes communities are still visible as “artifacts” (not often though).

For example blahaj defederated from lemmygrad one year ago, but I can still view !ukraine_war_news@lemmygrad.ml (but posts from after the defederation don’t show up)

And for example I can still see posts and comments from @yogthos@lemmygrad.ml before defederation.

Huh in that case I wonder if both instance and defederation works by sort of pausing/suspending the new content updates.

Sort of like how Newpipe works is that new content could be available on your home/sub feed but won't show up unless explicitly updated (by swiping down). Although for this analogy to work, banning would be equivalent to a filter/block in Voyager although it'll only work for newer content?🤔

That's my new guess anyways, not sure if it'll help!😅🤗
