Mastodon should ask you to pick a "moderator" not an "instance".

The latter is obscure technical detail. The former is about people, and power, and explainable to anyone.

"You pick which person or organisation you want to decide who and what is banned. You can change it later."

@moh_kohn Exactly! And someone you pick to filter what you see should not have the power to later prevent others from seeing you. I think right now #nostr is probably the best protocol for the basics.
