Not sure if you understand how nostr work. (Don shoot us for this)

– All clients offer a delete option that permanently hides a note that a user requested to delete, even from other clients

> nostr, unlike other, is decentralized. notes are not store on clients but on relays. Usually the relays you connect your client to. Some are free, some charge a fee. The free one are under no obbligation to delete notes at people's will.

To solve this problem you can run your own relay and make it reachable by the network. In that way you manage your data.

– All note types are editable to allow users to fix tags and typos

– Users can un-like and un-repost content if they change their mind

> that depends on the client

A

– Account deletion allows for all content posted by a user to be purged

> similar to the first point
