@taylan I agree that instance admins are often over-reacting with instance blocks, but I don't see how moderation can work on a large scale without such mechanism.
The situation can be improved by making identity decentralized. I've been working on it: https://codeberg.org/fediverse/fep/src/branch/main/fep/ef61/fep-ef61.md
This solution allows full account migrations (not just followers), and multi-homing. A bit like Nostr, but "instances" still exist as moderation domains.
