Finding a server to move to is easier than most people realise.

There are human-curated lists of servers at https://fedi.garden and https://joinmastodon.org/servers

All these listed servers promise to obey these rules:

-Active moderation against racism, sexism, homophobia, transphobia
-Daily backups
-Two or more people with admin access
-3 months warning if they are shutting down

You can keep your followers, follows, blocks, mutes and bookmarks when you move. Here's how: https://fedi.tips/transferring-your-mastodon-account-to-another-server/
