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.
Não é só questão de preferência da "instância". Isso é um limite que o desenvolvedor do #Mastodon fixou no programa. Ainda bem que é software livre, então, quem se dispõe a manter as alterações necessárias faz isso em seu servidor.Além disso, as instâncias desta federação não estão sujeitas necessariamente ao Mastodon. O protocolo ActivityPub, que regula o padrão de troca de informações entre elas, pode ter implementações diversas. Por exemplo, meu servidor não é Mastodon e sim #SNAC, sem esse limite. 
Huge thanks to @grunfink@comam.es and all contributers!! 🎉
Quote-posting your own posts is now allowed (do it by adding RE: https://example.com/you/post-id in its own line in a post body).
The Mastodon API can now be disabled by setting the mastodon_api directive to false in server.json (no need to compile it out).
Fixed a crash in chunked transfer encoding code (special thanks to Sergey Bronnikov for bringing this to my attention).
Tweak to JSON loading code to circunvent fmemopen() issues on Illumos / OpenIndiana systems (contributed by aleteoryx).
Mastodon API: Fixed error in voting code (contributed by uilebheist), more aggressive old data purging.

I noticed there's a command "collect_replies" and it sounds like this would get the replies so they show up... but it doesn't seem to do anything?
I wonder if I'm misunderstanding how fedi works or what that command does. Can one instance A ask another instance B "give me all replies to that post!" even when the replies are from even other instances C, D, E etc.?
Event type objects like those generated by Gancio or Mobilizon are understood and its special data (location, start / end time, etc.) shown.I've noticed from the snac(8) manpage that there's some support for Events in snac, and I've seen one post that had an "Event" tag attached to it. what's the current state of ActivityPub Events? are we able to create Events from snac?
I have two emoji,
and
, which I have updated since I first created them, but most servers haven't updated their caches.
Hashtag following also allow URLs to RSS feeds of ActivityPub objects (like e.g. https://mastodon.social/tags/ThankYouTuesday).
Users can now configure a webhook to receive an HTTP POST for every notification. This can be useful for implementing bots that react to activities, like autorepliers, chatbots or interactive textual games (see snac(1) for more information).
The number of pending follow confirmations is shown next to the "people" link.
Faster performance metrics (contributed by dandelions).
Improved lowercasing in hashtags (contributed by postscriptum).
A search-by-url tweak for implementations that return 200 for invalid webfinger queries (e.g. piefed).
Mastodon API: added follow confirmation endpoints, fixed collisions in attachment file names.
Fixed potential crashes in attachment uploads.

Notifications are now shown in a more compact way (i.e. all reactions are shown just above your post, instead of repeating the post ad nauseam for every reaction).
New command-line option unmute to, well, no-longer-mute an actor.
The private timeline now includes an approximate mark between new posts and "already seen" ones.
Fixed a spurious 404 error in the instance root URL for some configurations.
