So do you think anyone can create a new instance or they are made up by the administration? I am confused lol.
@PorFavorDama yeah anyone can create an instance if they want. Instances federate with each other once people start following other users across instances.
This project is entirely open source on GitHub and it's relatively easy to deploy using docker.
@PorFavorDama instances.mastodon.xyz has a good list. Also, there is a list of instances on the GitHub repo.
To create one, you will have to clone the repo and host it on a server you own.
