@Gargron No it's not. You can't even follow all your friends on Mastodon. I tried for over a year, and this is the fifth account I made on the Fediverse. but again and again some vainglorious admin hit the "fediblock" button. Then I was told I'm not allowed to criticize admins and causing too much trouble with my complaints.
Goodbye Mastodon, hello Bluesky.
