If you have issues with your Mastodon account and are on mastodon.social, take these steps:
1. Go to https://instances.social/ & do the wizard
2. Select any instance that pops up that looks nice to you
3. Create an account there
4. Set up an account alias by going to Settings -> Account -> Account Settings -> Moving from a different account
5. Move your account by going to https://mastodon.social/settings/migration
The #Fediverse is distributed, you don't need to be on the most popular instance to participate.
