Instances

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.

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 or sovereignist contents by marking them as noxious.

To report any issue, technical or non-technical, or to suggest instances to exclude according to the above criteria, please contact us at our e-mail address, masthelp[at]insicuri.net.

We currently count 10,784 Mastodon instances, with 9,272,359 users (1,001,949 active during last month) and 1,062,543,680 published statuses. [Show Threads moderation statistics]

Threads moderation statistics

These statistics on the status of Threads moderation are based on the list of moderated instances, which is accessible only on some instances, and on the list of instances adhering to the Anti-Meta Fedi Pact.

Federation policy

For security and safety reasons, we do not presently publish our instance-wide moderation policies to the public, but instance users may view the policy by logging in.

Utmost care is taken to prevent metadata leakage to other instances, including the use of authenticated object fetch requirements. Administrators of other instances are encouraged to send any concerns or questions to the admin team concerning our instance-wide moderation policies, including to request a list in Mastodon's standard CSV format of current moderation policies.

Moderation policy (Code of Conduct)

User behavior and content are required to comply with US federal laws and the Revised Code of Washington. Content and behavior which is not in compliance is expressly forbidden and may result in account termination and, in some cases, reporting to authorities as required for our own compliance.

User behavior and content is also expected to abide by the server rules, outlined below:

Organization and project accounts are by invitation only.

Accounts belonging to organizations and project accounts are by invitation of the moderation team. These accounts are expected to uphold the values of this community to a greater extent than normal accounts.

For a multitude of reasons, corporate accounts are not welcome on Treehouse. We recommend running dedicated instances for corporations.

Identity verification requirement to use this server.

In order to sign up for an account, your identity must either be verified by the moderation staff, or you must be explicitly invited to use the instance by a current member.

To streamline the identity verification process, please provide links to other examples of your presence online. This will allow our team to determine if you would be a good fit for our community.

Be kind to each other.

To foster a healthy community, we expect interactions to be kind and empathetic. If you find yourself getting annoyed or frustrated with a conversation, we encourage you to step away for a moment and regroup your thoughts.

No violence.

Content which describes explicit violence towards others is explicitly forbidden. Ranting and similar content is allowed but it may be beneficial to the community at large and its moderation staff to use a content warning to clarify the intention behind the content.

No fascism, white supremacy, etc.

Content relating to fascism, neo-fascism, Trumpism, white supremacy, male supremacy, alt-right ideology, and so on, is explicitly forbidden. Accounts trafficking in this content will be banned with no possibility of appeal.

No colonialism or nationalism.

Content relating to nationalist or colonialist ideology is explicitly forbidden. Accounts trafficking in this content will be banned with no possibility of appeal.

No racism, homophobia, transphobia, etc.

This instance is intended to be a safe space for LGBTQIA+ and PoC people. Accounts which are not compliant with this policy will be banned with no possibility of appeal.

No religious extremism.

Content relating to the promotion of religious extremist ideology is not allowed, for the same reasons that all of the other content types above are not allowed. Accounts trafficking in this content will be banned with no possibility of appeal.

Use content warnings for explicit content.

Explicit content such as, but not limited to, adult content, content including extreme gore, depictions of violence, and any content which may trigger panic responses in individuals with common phobias (such as arachnophobia) must be marked sensitive and content warned.

If moderators have to fix your posts to comply with this policy, you will be given a warning. After multiple warnings, your account may be suspended or terminated at the discretion of the moderation staff.

Reporting violations of this Code of Conduct.

Users may report content which they believe to be either illegal or a violation of server rules in the Mastodon web interface.

Long description
This is supposed to be a comfortable place for scientists and journalists to be. Think of it as a cocktail party; behaviors that are unacceptable in that context are unacceptable here.

DMCA agent: Charles Seife (@cgseife, or cgseife at gmail)
Instance rules
  1. Users may not be anonymous, at least while this site is in its infancy.
  2. Users should be scientists, journalists, or scientific/journalistic institutions or publications.
  3. Please be as kind, polite, and understanding as you would be in a cocktail party of friends and strangers. Harassment, racism, sexism, antisemitism, homophobia, transphobia, or bullying will get you shown to the door.
  4. No trolling -- combative, out-of-left-field responses to posts seeking argumentation rather than genuine discussion are not welcome.
  5. Avoid spreading misinformation. Obviously this can be difficult to delineate, and there are many gray areas, but repeated and/or deliberate spread of misinformation is not allowed.
  6. Relentlessly pushing a theory or idea -- in its extreme, crankery -- is not welcome. The line is blurry, but it can be crossed. Again, think cocktail party... feel free to discuss ideas, but if people are likely to start sidling away, it's an issue.
  7. The Content Warning flag should be used for NSFW content; NSFW media should be marked as sensitive.
  8. Users must be 18 or older.

FAQ

What is Sigmoid Social?

Sigmoid Social is a Mastodon instance for people researching, working on, or just interested in AI. We went live on 11/04/2022.

Who should join Sigmoid Social?

You should join Sigmoid Social if you would like to be part of a Mastodon community primarily focused on discussing AI. We do not gatekeep who can join; it does not matter whether you are a researcher, engineer, hacker, student, artist, or just curious.

Who runs Sigmoid Social?

Sigmoid Social is administered and maintained by The Gradient. The Gradient is a non-profit and volunteer-run organization with the mission of facilitating discussion within the AI community. We were founded in 2017 by a group of students and researchers at the Stanford AI Lab. Our current projects include The Gradient Magazine, The Gradient Podcast, The Update newsletter, and Sigmoid Social.

Should I only post about AI?

You can feel free to toot about anything at all, as long as it complies with the Code of Conduct. We may however ask you to migrate to a different instance if your focus is not AI at all.

Should I only post in English?

This server supports translation, so it is ok to post in other languages than English. But, as English as the primary language here, that should ideally be the primary language you use. If you do post in other languages, please tag your posts with the appropriate language label.

Will you ban me for X?

We will take appropriate moderation measures against any violations of the Code of Conduct. We also reserve the right to take actions in the best interest of the community in situations we deem harmful but do not clearly violate the Code of Conduct. We will generally lean towards promoting free expression and issuing warning and restrictions rather than bans, but this is absolutely not a free-speech-above-all platform.

How can I help cover costs?

You can support us on Patreon or Kofi!

How can I share suggestions for Sigmoid Social?

You can message The Gradient via Mastodon, email, Twitter, or pigeon.

Where is my data stored?

Sigmoid Social is hosted by MastHost, a fully managed Mastodon hosting service provided by WAP – Web Access Platforms. WAP is a one-person company 100% owned and administrated by Hugo Gameiro. All data storage and processing is done through MastHost.

What happens if The Gradient can no longer maintain Sigmoid Social?

In the case that our current team can no longer run Sigmoid Social, we will attempt to transfer control of it to another non-profit entity within the AI community. If we are unable to do this, we will announce the closure of Sigmoid Social within at least 30 days to allow users to transfer their accounts to other Mastodon instances.

Can you access my private DMs?

The only way we can access private communications from Sigmoid Social is through exporting the database stored by MastoHost. We will do this periodically for the purpose of storing backups, and in case we have to migrate to another hosting solution. We will not inspect the database for any other reasons. Regardless, we recommend not sharing any private or secure information on this platform.

What is your policy in AI Art and NFTs?

This instance is a great fit for anyone who wants to post AI art - we fully support it. We are also OK with NFT promotion, as long as it relates to AI art and is not spammy.

Why does the banner spell out "Sigmioid"

We generated our banner using MidJourney (a text-to-image AI tool), and intentionally picked out an image that contained a typo as a little in-joke about these tools.

Recommended Practices & Mastodon tips

Here are some recommended practices for helping make Sigmoid Social a great place for everyone here:

  • Browse the local feed when starting out. Mastodon has three types of feeds: home (people or hashtags you follow), local (all posts from this instance), and federated (all posts from this instance and any users from other instances that are follow by anyone on here). Until you follow some people or hashtags, the local feed is your best bet for discovering content.
  • Use hashtags. Mastodon does not have an algorithmic feed, so hashtags are often used for finding content relevant to your interests. So, using hashtags will make it easier for others to find and follow you, and for you to find others as well. We list a set of recommended hashtags below!
  • Use the unlisted privacy setting in replies and threads. The default post privacy in Mastodon is 'global', which gets posted to the local timeline, whereas 'unlisted' is only shown when browsing the replies to a given post. Using unlisted for most replies and threads makes the timeline less cleaner and nicer to browse.
  • Look into the non-official apps for Mastodon. There are some apps not made by Mastodon that provide an arguably better frontend. Examples include Tusky and Toot!
  • Consider using content warnings/content labels. The CW button when writing posts stands for 'content warning', and then you include one in your post only the text for it is shown unless a user presses a button to see the rest of the post. We recommend using it for sensitive content, but you can also use them like a subject line or TLDR as well!
  • Explore Mastodon notification options. Mastodon allows you to mute various types of notifications, which can make it easier to focus on just replies and ignore favorites or boosts if you prefer to do so.
  • Report any content you think might violate the code of conduct. Moderation on Mastodon primarily relies on the users reporting objectionable content, at which point our mods can take care of it. Reporting bad content will make the experience on Sigmoid Social better for everyone!
  • Aim to be generally civil and friendly :)

Code of Conduct

Sigmoid Social is dedicated to providing a harassment-free experience for everyone.

We want this community to maintain a fun, pleasant, and harassment-free experience for everyone, regardless of gender, gender identity and expression, sexual orientation, disability, physical appearance, body size, race, or religion. In keeping with these aims, we do not tolerate harassment of participants in any form. Participants asked to stop any harassing behavior are expected to comply immediately. Anyone who violates this code of conduct may be sanctioned or expelled from Sigmoid Social at the discretion of the organizers of the Gradient.

Harassment, including the following activities, will not be tolerated:

  • Offensive comments related to gender, gender identity and expression, sexual orientation, disability, mental illness, neuro(a)typicality, physical appearance, body size, age, race, or religion.
  • Unwelcome comments regarding a person’s lifestyle choices and practices, including those related to food, health, parenting, drugs, and employment.
  • Deliberate misgendering or use of ‘dead’ or rejected names.
  • Gratuitous or off-topic sexual images or behaviour in spaces where they’re not appropriate.
  • Physical contact and simulated physical contact (eg, textual descriptions like "hug" or “backrub“) without consent or after a request to stop.
  • Threats of violence.
  • Incitement of violence towards any individual, including encouraging a person to commit suicide or to engage in self-harm.
  • Deliberate intimidation.
  • Stalking or following.
  • Harassing photography or recording, including logging online activity for harassment purposes.
  • Sustained disruption of discussion.
  • Unwelcome sexual attention.
  • Pattern of inappropriate social contact, such as requesting/assuming inappropriate levels of intimacy with others. Sigmoid Social is intended to be a welcoming platform, so while friendships in support of research are encouraged, note that Sigmoid Social is not a dating platform. Flirting or other unprofessional behavior may make someone uncomfortable. If a member requests another member to stop this type of behavior and it continues, it will be considered harassment.
  • Continued one-on-one communication after requests to cease.
  • Deliberate "outing" of any aspect of a person’s identity without their consent except as necessary to protect vulnerable people from intentional abuse.
  • Publication of non-harassing private communication.
  • Impersonation with the intent to deceive users (satire is ok).
