Edit:

I reached out to Lemmy World admins (!lwadmin) and they said:

If a user is banned on their home instance then it federates to others, if banned on instances other than their home, it doesn’t

    It doesnt federate its just that he cant write anything on the home instance => so he cant post on non local instances he is locked out of his account

      It could’ve changed since then but back when I ran my own single-user instance I had bans federating in from other instances listed in my admin panel.

        Ok weird as it is useless tbh. As the user can only post FROM their account and because of that its impossible to login from non local instances.

          It’s not useless, it’s so that the ban can be displayed on other instances. If it weren’t propagated, you couldn’t know if someone was banned without explicitly looking up their profile on their home instance.
