## Disclaimer
`Following instances skipped`: closed registration *at the moment of checking*, running old code, theme / description not understood due to language barrier or scarce description, long blocklists, experimental servers.

Add your own themed Mastodon instance by opening an issue or via [MR](https://gitlab.com/distributopia/masto-world-overview). If your server already has many users, it will be nice of you to let other instances grow, for a healthier decentralization.
