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

If they’re banned from their own instance, that ban federates out and they’re completely banned off that account.
If some other instance bans them, that ban is instance specific and that person can still interact with communities and people from other instances, except the one that banned them.
