Screenshot of BBC's message when trying to join their instance: Signing up on Mastodon Mastodon is decentralized, so no matter where you create your account, you will be able to follow and interact with anyone on this server. You can even self-host it! On this server Unlike most Mastodon servers where you can sign up for a personal account, we're only using this instance to host BBC accounts; it’s a place for us to publish in the Fediverse. If you have a Mastodon (or other ActivityPub) account from another server, then you can easily follow our accounts. On a different server Since Mastodon is decentralized, you can create an account on another server and still interact with this one.
