So I am hosting an instance for myself and I have noticed that when I go into Admin Settings (cog symbol) I get a beefy list of Banned Users on the right but I didn’t ban any of them.

Is this just unintuitive UI?

The way I thought this works is when I, as admin, ban user from my instance then that user won’t be able to log-in here anymore but when I ban a user from other instance then anything from that user won’t show up at all on my instance (kind of like shadow ban, but only for users of my instance).

E: I am the only admin/mod on my instance - the only user able to ban users, so there is noone else who could have banned someone without my knowledge.

Upd: Bans are federated and it makes sense, thanks /u/[email protected]
