Is there a nostr client that allows you to post things with an expiry? So the events will be deleted automatically after some time.
Discussion
First question would be if there's a NIP for that. Obviously it's up to relayers and clients to actually delete it, so such a feature might give a false sense of security.
NIP 9 and NIP 40 allows clients to request deletion of events. Relays delete them most of the times. Not looking for security but to avoid manual deletion of events after shitposting. A user could enable expiry, shitpost for a few hours and forget it.
You have NIP-40 but that's formulated as "SHOULD be deleted by relays". As you might know, any relay could just archive the event or simply refuse to delete it.
Oh sorry, just saw that you said "client". Not sure I've actually seen a client with that feature..
