feature: hide profile posts
i dont really use reddit much, but i noticed there is a privacy feature to hide own posts from profile.
i think this could be useful on nostr too, especially in reddit like client like #substr where you may not want to disclose all your activity across different subs.
i think this would be possible on nostr also.
simple derived nsecs would work for the privacy:
unique_priv_key = sha256(privkey + substr_name)
but then the problem is that the profiles are indeed distinct and not the same.
can you come up with a cryptographic solution that allows reuse of same identity (pubkey) while in some way hiding overal profile activity? might be a bit challenging, but is it impossible or not?
