"My instance Admin gets into a fight"
"Friends’ instances defederate from mine"
"I want to see my friends' posts"
The same happened to me. It wouldn't happen to involve .art, would it? The Queen of bullying and punishment by selfish block abuse? And reputation attacker?
I need a good reason before I block an instance, even if the instance Admin is a jerk. Members come first. I wish Admins would understand the impact on people when they block.
You are right to want to stay connected to your friends. You are right to expect it. You were made an implicit promise when you joined Mastodon. Someone broke the promise.
I'm sorry you've had to deal with this nonsense.
