What is Mastodon social media?

Mastodon is a type of social network that has recently surged in popularity. While it’s more widely used by adults, its popularity may lead children and young people to explore the platform.

Learn about Mastodon to help you make the right choice for your family.

What is Mastodon?

Mastodon is an open source software that has led to a series of alternative social media sites. The social networking sites are hosted on decentralised servers, which means it is not owned by one person or company. The free and open source software was founded in 2016 with stable release in November 2022.

Like Reddit, users can find servers to align with their interests and beliefs. However, its layout resembles Twitter as does the use of hashtags and ‘toots’ (the origial name of Mastodon’s posts).

Mastodon gets its name from the prehistoric mammal of the same name. Branded cartoon imagery of the animal is used across the social media website and app. ‘Toots’ also come from the noise such an animal could make from its trunk.

How it works

To join Mastodon, users must choose a server to start with. Some of these servers are private and require you to apply for an invite. Others are accessible without this requirement.

The main Mastodon website suggests different servers that have rules in place against racism, sexism and transphobia. However, other servers are searchable once on one of the servers.

Each server has its own moderators and set of rules for users to follow. While Mastodon has a privacy policy, it only refers to the navigation site from which users browse servers. Otherwise, servers are responsible for setting their own privacy policy. This may differ from one server to the next.

Users can also join multiple servers, which act as their own social media sites. You can redirect one profile to another.

Once joined, you can follow users and talk to people from any Mastodon site through suggestions or searching hashtags. You can also share your own posts. The standard character limit is 500 but some servers may allow more.

Safety concerns on the Mastodon social networks

No age verification

Unclear age minimum

Because Mastodon is decentralised, each server sets its own rules. As such, it is not regulated by wider governing bodies.

Some servers include age minimums in their privacy policy. However, Mastodon accounts do not have age verification. As such, these requirements are easy to get around.

Limited privacy settings

Lack of protection for young people

Mastodon is generally popular among adults and especially those in tech industries. While the social network has a few settings to limit sensitive content and who can see your posts, it is not robust.

Increased online risk

Risk of grooming, cyberbullying and more

While Mastodon celebrates providing more freedom for its users, this freedom could negatively impact young users. With controversies on other platforms, some users took to Mastodon as a means of speaking more freely. Unfortunately, this sometimes leads to cyberbullying.

Additionally, with less moderation than larger social media platforms, young users especially are more vulnerable to grooming, scams and other online risks.

Sudden popularity

Increase in users due to controversy

Because of other social networking controversies, Mastodon saw an increase in popularity. This increase isn’t necessarily bad, but a sudden increase in users may lead to new risks. So, it’s important to stay vigilant.

How to keep young people safe

Most social media networks require its users to be thirteen or old, so it’s a good idea to follow this guideline for Mastodon as well. However, some servers may only be appropriate for adults. As such, it’s important to talk to your teen about their online use.

You may also want to:

  • talk about its place in news: help them understand what makes it popular among older users along with its benefits and drawbacks. An open discourse will help them feel heard. Additionally, they may feel more confident coming to you when they need help.
  • talk about news and information on social media: most young people now get their news from social media. Therefore, it’s important they know how to think critically about what they see on Mastodon (or any social network).
  • set parental controls: while Mastodon itself has limited controls, you can set devices and browsers up to limit content. Restrict access to the app via app store and smartphone settings, or use browser and broadband settings to do the same.
  • use privacy settings: to limit content and enhance privacy, have teens make use of the platform preferences available on Mastodon.

What are Mastodon’s preferences and safety settings?

Mastodon offers the following preferences and features to enhance user safety across servers:

Blocking and reporting

Block and report users

Like other social media platforms, Mastodon includes options to block or report users on your server. Simply go to their profile to do so. Note: this can only be done from a server you’re apart of. The option won’t show up otherwise.

When you report user or content, the moderation team reviews this. However, how much content is moderated may change from one server to the next.

Mute users

Mute harmful content or users

Similar to other social networks, users can mute others on Mastodon servers. This keeps you from seeing users in your home feed either through their own posts or through others sharing their content.

Mutes can be set for a certain amount of time. Also, you can choose whether to keep getting notifications from them.

Filter content and words

Customise your feed

Media marked as sensitive content and posts with content warnings are automatically hidden. Additionally, users can set up filters in Home and lists, Notifications, Public timelines, Conversations and Profiles. These filters include chosen words or phrases you do not want to see in your feed.

Filter options

When setting up filters, there are two options to consider:

  • filtered posts will still show up in your feed, but you will see a content warning that automatically hides it until you choose to view it
  • filtered posts are completely hidden from your feed and inaccessible by you

Set post privacy

Control who can see you

Like other social networks, you can remain relatively private from other users. You can set up your posting privacy to control who sees your shares — everyone or those who follow you. Another option is to remain ‘unlisted’ so your posts stay hidden from searches as well.

Additionally, you can hide your profile from public searches.

Other alternative social networks to watch

As more people talk about alternative social media apps and platforms, it’s important to keep an eye on new ones that may be similar to Mastodon.

Hive Social

The Hive Social app has increased in popularity. While many of its users may be adults like on Mastodon, its popularity may lead teens to explore it as well. Additionally, its user interface and style is more similar to apps like Instagram that may appeal to younger users. Its messaging around inclusivity may increase this appeal.

Created fairly recently by students in college, younger users may be more likely to sign up to the app. Hive Social allows users to add music to their profile and share their pronouns and astrological signs. The music addition like MySpace once had may also prove exciting to teens.

Hive Social combines elements from other modern social media platforms such as the text and image style of Instagram and polls from Twitter.

Its relatively young age may mean it takes some time for it to become popular. However, if your teen shows interest, make sure they know it’s for those 13 and older. Then, help them make use of the safety features available. These include:

  • hiding mature content
  • hiding words and phrases you don’t want them to see
  • controlling who can see their comments
  • setting their account to private
  • using report, block and mute features


The Tribel social network is a free alternative social media platform often mentioned alongside Mastodon. It claims to offer a better browsing experience with posts reaching audiences chronologically instead through an algorithm that might push posts to the bottom of a feed.

Tribel offers users more customisation of their feed and encourages users to become star contributors by sharing with selected audiences.

They have faced some controversy on their data collection and privacy, including a now-amended policy that all content posted belongs to them. Additionally, Tribel’s owners also own a website and Facebook group often associated with false or exaggerated information largely around American politics.

While the platform allows children aged 13 and over, the Google Play Store recommends parental guidance and browser blockers recognise it as containing security risks, which may involve inappropriate and unregulated content.

Additionally, Tribel does not seem to have strict content guidelines. Rather, posts must be “intelligent” and for the right audience. They do not allow Covid-19 misinformation or abusive posts.
