Are new users leaving because they can’t delete or other factors? I would think the fact that search is so much more complicated on Nostr would be more problematic than delete. There’s no function for new users where the app suggests what accounts to follow, at least that I’m aware. Which I would think leads to capture of new users on other sites. Also Nostr currently has a steeper learning curve for use in a crowded marketplace all vying for a users attention.
