The mastodon.online server is an instance of the Mastodon open source software (OSS), created and maintained by Mastodon GmbH. Our team runs this server to provide a safe social home for anyone, especially for newcomers to the social web, and as a reference implementation of the Mastodon software. For these reasons, we take a strong stance against content and speech that does harm.
If this doesn’t sound like the right place for you, we encourage you to explore other Mastodon servers by visiting our
Server Directory. If you already created an account on mastodon.social and want to move to a different instance, you can learn how to do so
here.
Our community standardsSigning up for an account on this server means you agree to follow the server rules below, and our extended community standards
here. Our
Help Centre has more information about
using Mastodon and
our community.
When accounts or content on servers we moderate violates our server rules and standards our enforcement is proportional, context-aware, and designed to educate before punishing when possible. When accounts or content on servers we moderate violates the law, we act swiftly to minimise harm.
