I'd guess that most instances with several thousand users will be around for quite some time. There are lists that show that. Most instances have a public page you can check out to see the instance's vibe. EG https://mastodon.xyz/public https://mastodon.xyz/public , https://fosstodon.org/public https://fosstodon.org/public Once you've found a new instance, you can transfer your followers to it. This Feditips page tells how to move your 'mutes, blocks etc'. https://mstdn.social/@feditips/105317854827203241 https://mstdn.social/@feditips/105317854827203241 Remove that number at the end and there are a lot more Feditips. One tip: you can easily subscribe to any Mastodon account through an RSS reader ... add '.rss' to the account's public page, there's your feed!
