About This Search Engine

This search engine for Mastodon instances is based on a database that gets updated by our crawler every night (CET).

Instances are considered new for 30 days after they are discovered (if you already have an account on the Fediverse and want to receive one daily post with a summary of the new Mastodon instances that our crawler discovers daily, you can follow @nmiab@kolektiva.social; alternatively, you can also view them here).

When an instance has not responded to our daily checks for more than 30 days it is no longer considered in statistics and searches and it gets checked only on the first of the month, rather than daily, until it possibly responds again, or until its last succesful check is one year old; in this latter case, from that moment it gets checked only on the first day of each year.

“Random ordering” of results varies daily.

Default search criteria reflect our fondness for a decentralized and egalitarian Fediverse and our attempt to exclude instances accepting fascist, racist, sexist, ableist, sovereignist, pro-nuclear and pedopornographic contents by marking them as noxious.

To report any issue, of any kind, involving mastodon.help, or to suggest instances to exclude according to the above criteria, please contact us at our e-mail address, arbuk+masthelp[at]disroot.org.

Important Notes for Instance Administrators

If you don’t want your instance to show up here, please e-mail us at arbuk+masthelp[at]disroot.org.

If your instance is behind a web firewall such as Anubis or Cloudflare, and you want it to be listed here, you must configure the firewall to allow our bot, which makes no more than a dozen HTTP requests per day, to connect to your instance, by whitelisting it by User-Agent and/or IP address. Our bot’s User-Agent is mastodon.help; the IP address from which it makes requests is the same as this site’s, 65.108.133.80.

THICC.HORSE

Thicc.Horse is an adult community that empowers users to explore, share, and celebrate who they are and what they love.

We believe that the web needs spaces that:

  • Are body & sex positive
  • Are accepting of all identities and sexualities
  • Are open to furries, ferals, therians, and monsters
  • Allows adult content, including kink and uncommon attractions
  • Bans accounts that mass post stolen content
  • Promote being respectful & friendly
  • Are free from monetization

Expectations

  • Act in good faith.
  • Treat others as they would like to be treated.
  • Listen if Thicc.Horse staff issues a warning.

Short description
A place for bats and bat friends to squeak at each other in the belfry
Long description
BatChats is a furry and LGBT+ friendly server, for bats and friends of bats to interact! It may be small, but it is good.

Note: After a recent increase in spam from my instance, I've had to turn on registration approval. Will approve as promptly as I can!

  4. If you're sharing a spoiler from TV/movie/other media, mark it as spoilers!
  5. No personal attacks, homophobia, transphobia, or hate speech
  6. No sharing someone's PII (address, phone number, social security number / other government ID numbers) without their explicit consent
  7. No means no. If someone asks you to stop responding to them, your business with them is done. Further interactions are harassment and are not allowed.
