Maybe something to clarify with #HolosSocial. There is a full moderation system like on any Fediverse instance. Moderators can ban accounts. But relays are dumb by design: your identity and data belong to you, not to the relay. A ban is like a relay going down, you don't lose everything. You can move to another relay and keep all your followers, following, and data. With a custom domain the transition is seamless, otherwise it works through standard #ActivityPub migration.
