    Those aren’t actually lemmy.world communities.

    Everything on that list is a community on that instance (whatever it is - lemm.ee I guess).

    For example, a post from a lemm.ee account to AskLemmyWorld@lemmy.world is actually a post to an entirely separate community - AskLemmyWorld@lemmy.world@lemm.ee That lemm.ee community is a mirror of the lemmy.world community (and of all the other communities on all the other instances that mirror it.

    That’s how federation actually works. You never actually leave your host instance, and what seems like a post to a community on another instance is actually a post to a locally hosted mirror of that community.

      to add to that, Lemmy currently does not handle site bans well if it’s not a home instance ban, as instances don’t keep track of which other instances have banned which users. this should get better with 1.0 though, as a PR to improve that was recently merged.

      for now, there is a band-aid solution that federates community bans for all communities local to the instance the user got banned from, but that only includes communities that the user previously participated in, so they’ll still be able to participate in the local copies of other communities from the instance they’re banned from, it just won’t fully federate out.
