For a community, you *have* to ban early and ban often, and defederate early and often.
As an admin, it's your job to protect the ✨vibes✨ of your space, to promote community, and to remove elements that are toxic or harmful.
A service doesn't work the same way. It isn't attempting to create (or promote) a specific vibe, it's just *there*. You make of it what you will, find what you will, and (as an end user) block what you will.
The admin "just" makes the service available.
A bunch of technomancers in the fediverse. This arcology is for all who wash up upon it's digital shore.
