jrollans.com 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.

One point that I keep seeing with these types of articles is that the person affected has “no history of mental illness”, who is someone “normal”, and often “intelligent”.
