Weird Federation Question with Banned user.

So we have A (aussie.zone) H (hackertalks.com) S (slrpnk.net) and D (dubvee.org)

• UserS is banned from dubvee.org but not the community
• UserS respond to a post from H, and H and A see this comment
• D does not see UserS's comment (makes sense, since they were banned).
• S has no community subscribers
• S does not see H, or A's response to UserS's comment

• 2 - Why does A see UserS's comment at all?
• 3 - Why doesn't S see A's response, or H's response to the comment? No local subscribers?
