Mastodon

How do I find a Mastodon server that suits my advocay for a better world?

Finding a Mastodon server (instance) focused on positive change, activism, advocacy, and social good is a great way to connect with like-minded people who want to make a difference. Because Mastodon is organized by community interests, there are several dedicated servers built specifically around social causes, environmentalism, and advocacy. - Here is how you can find a server that matches your passions:

1. Use Official Server Directories

Mastodon provides a curated directory to help users find servers based on their specific interests or categories:

• The Official Server Picker (joinmastodon.org/servers): You can filter servers by categories like Activism, Technology, Art, or Regional/Local.
• Look for specialized servers: Within the directory, you will find communities specifically hosted by advocacy groups, environmental organizations, or social justice collectives.

2. Check Dedicated Community Directories

• Instances.social: This is a popular community-run tool that lets you search for Mastodon servers using keywords or filters (such as language, active user counts, and topics like climate action or human rights). It gives you a detailed breakdown of each server's rules and moderation style before you join.

3. Key Themes to Look For in Advocacy Servers

When browsing servers focused on making the world better, look closely at their profiles:

• Shared values: Read their "About" page and code of conduct. Servers focused on advocacy often have clear guidelines protecting marginalized groups and promoting constructive discourse.
• Interoperability: Remember, joining one server doesn't isolate you. Even if you join a server focused specifically on environmental activism, you can still easily follow, reply to, and collaborate with users on thousands of other servers across the entire Mastodon network.

How do decentralized platforms like Mastodon keep user data private compared to traditional social media?

Decentralized platforms like Mastodon protect user data differently than traditional social media by fundamentally changing who holds the data, how it is monetized, and how algorithms track behavior. - The structural differences allow for distinct privacy controls:

1. No Central Corporation Monetizing Data

On traditional social media, a single corporation owns the central servers and relies on harvesting your data (clicks, search history, time spent on posts) to build targeted advertising profiles.

• The Mastodon Model: Mastodon is open-source software operating on independent servers called "instances". Because individual communities, universities, or volunteers host these servers—often funded by donations or subscriptions rather than ads—they have no financial incentive to track your behavior, sell your profile, or build targeted ad algorithms.

2. Distributed Control Instead of a Single Data Giant

Traditional platforms store all global user data in massive, centralized corporate data centers vulnerable to single-point breaches or corporate overreach.

• The Mastodon Model: Data is spread across thousands of independent nodes. If one server experiences a security issue or changes its policies, it doesn't compromise the entire network. Users choose which server/administrator they trust with their registration data when they sign up.

3. Chronological Feeds (No Behavior Tracking)

Traditional platforms use black-box algorithms designed to maximize screen time by tracking what makes you angry or engaged, feeding you content based on deep psychological data profiles.

• The Mastodon Model: Timelines are strictly chronological (either local to your server or across accounts you choose to follow). There is no automated tracking algorithm analyzing your habits to manipulate what you see.

4. Granular Privacy Options

Mastodon provides direct controls over individual post visibility:

• Public: Visible to everyone on timelines.
• Unlisted: Visible to followers, but hidden from public explore/discovery grids.
• Followers-only: Restricted strictly to your approved followers.
• Locked Accounts: You can manually approve every single person who attempts to follow you.

Important Privacy Nuance: While Mastodon stops corporate data harvesting, it is not end-to-end encrypted. Because messages pass through servers to communicate across the network, the administrator of your server (and the server of anyone you send a direct message to) technically has access to that data. This makes choosing a trusted instance administrator an important part of privacy on decentralized platforms.

How do I choose a trustworthy Mastodon server or instance that respects user privacy?

Choosing a trustworthy Mastodon server (also called an instance) is the most important step for protecting your privacy on the network, since your data lives on the specific server you join. - Evaluating an instance involves looking at a few clear indicators:

1. Check the Server's Rules and Code of Conduct

Every Mastodon instance has its own set of rules managed by its administrator.

• Look for explicit privacy commitments: Check if the server explicitly states that it won't sell or share data, and look at how it handles user logs and moderation.
• Moderation standards: A good server actively moderates hate speech, spam, and harassment. Check if they have a clear anti-harassment policy and a responsive moderation team.

2. Review the Funding and Sustainability

Running a server costs real money for server space and maintenance.

• How are they funded? Look for servers funded by transparent public donations, crowdfunding (like Patreon or Open Collective), or the organization running it (like a non-profit, university, or privacy advocacy group).
• Avoid mysterious free servers: If a server is completely free with no explanation of who pays for it or why, it's harder to trust who is covering the costs.

3. Look at the Server's Size and Administration

• Single-admin vs. Organization-backed: Smaller servers run by individuals can be great and tight-knit, but if the admin decides to shut the server down, you have to migrate. Larger servers backed by recognized organizations or collectives often have more stable, long-term infrastructure.
• Server reputation: You can check tools like instances.social or the official Mastodon server finder to read reviews, check the server's uptime history, and see what other networks (instances) it is connected to or blocks.

4. Understand What Admins Can See

Even on a trustworthy server, server administrators technically have access to your direct messages and account settings. Because of this, it is best to join a server whose administrator or community aligns with your values, and remember never to share sensitive personal information (like passwords or financial data) over direct messages on any social platform.

How do I migrate my Mastodon account and followers to a different server?

Moving your Mastodon account to a new server is built right into the platform. While your past posts and media won't automatically transfer due to technical limitations, your followers can be automatically migrated, and your old profile will display a clear redirection notice pointing everyone to your new home. - The process requires a few sequential steps to complete safely:

1. Create and Set Up Your New Account:

Register a brand new account on the Mastodon server of your choice. Set up your profile picture, display name, and bio so people recognize you. It's also a good idea to post a quick welcome message letting your new server know you're migrating.

2. Export Your Data (Following/Block Lists):

On your old account, go to Preferences > Import and export > Export. Download the CSV files for the accounts you follow, as well as any mutes, blocks, or lists. (Note: You can also request a full data archive of your posts here if you want to keep a personal backup.)

3. Import Your Lists Into the New Account:

On your new account, go to Preferences > Import and export > Import. Upload the CSV files you just downloaded (like your "Follows" list) so your new account automatically starts following the same people.

4. Create an Account Alias:

To prove you own both accounts, go to your new account's settings:

• Navigate to Preferences > Account and scroll down to "Moving from a different account".
• Click "Create an account alias" and enter your old account's full handle.

5.Trigger the Follower Migration:

Now, go to your old account to finalize the move:

• Navigate to Preferences > Account and scroll down to "Moving to a different account".
• Click "Configure it here", enter your new account handle and your old account password, and click "Move followers".

What Happens Next?

• Your Followers: Mastodon will begin the process of automatically unsubscribing people from your old account and subscribing them to your new one. Depending on how many followers you have, this can take a little while to process completely.
• Your Old Profile: Your old account will instantly switch to a read-only "redirected" state. Anyone who visits your old profile will see a prominent notice letting them know you've moved to the new server.
• The Cooldown: Keep in mind that once you migrate, Mastodon enforces a 30-day cooldown period before you can initiate another move.

How do I download and save a full data archive of my old Mastodon posts?

To download and save a full data archive of your Mastodon posts, you can easily request and export all your personal data (including posts, media uploads, lists, and bookmarks) directly from your account settings. - The export process takes just a few steps:

1. Navigate to Import and Export Settings:

Log into your Mastodon account through a web browser. Go to Preferences (the gear icon or settings menu), click on Account in the left sidebar, and scroll down until you find Import and export.

2. Request Your Data Archive:

Click on Data export. Here, you will see checkboxes for various types of data you can include, such as your uploaded media files, posts, follows, and lists.

3. Generate and Download the Archive:

Click the Request button. Mastodon will begin compiling your archive in the background. Depending on how much media and how many posts you have, this might take anywhere from a few minutes to a few hours. Once it is ready, a download link will appear right on that page or be emailed to you, allowing you to download a .tar or .zip file containing all your data.

Who owns Mastodon?

Unlike traditional social media platforms owned by single, profit-driven corporations (like Meta or X), Mastodon is not owned by any single company or billionaire. - Instead, it is a decentralized, open-source project. Its ownership and structure work a bit differently:

1. Created and Led by Eugen Rochko

Mastodon was originally created in 2016 by software developer Eugen Rochko, who wanted an independent, open alternative to commercial social media. He maintains a central leadership role in developing the core software.

2. The Governing Entity

The core software and official branding are developed and protected by a non-profit organization governed by a board of directors (which includes people from fields like technology, digital rights, and non-profit governance).

3. Decentralized Servers (Nobody Owns the Whole Network)

Because Mastodon is built on open-source code and open web protocols (the "fediverse"), no single entity owns the entire network.

• Individual servers (instances) are independently owned, hosted, and moderated by different people, groups, universities, or local communities all over the world.
• If you join a specific server, that server is managed by its own local administrator, not by a central tech giant.
