I saw many artists going to Misskey.io because it’s main instance even English speaking ones until they gone back to twitter, stayed on Misskey or half measures. Then because of EN influx in mainly Japanese server , Misskey.io closed doors to non-Japanese add in fact that Misskey or rather any federated service can’t oblige to European Union protection standard which means they can’t operate in EU officially.
So I see lots of messages on Misskey about artists making blue sky accounts as well… All depends where they get more views I guess or have people supporting them around.
Everyone gives solid advice, so I will point you to trusty https://fedidb.org/software .
Mostly to see stats of Fediverse but also the soft that is available. Maybe you find one that suit you.
