fennell.dev is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
It's a well-known fact, that not even eating the #SIM card as #antisurveillance measure prevents feds from #tracking them 🙂

(The real problem is, that at least in #Europe, it's difficult to get an #anonymous phone number.)
