One thing I noticed on Nostr is after uploading an image, if I delete the related Nostr note (via a kind:5 delete), the media still remains on the media server, example Nostr Build website .

That creates "orphaned media" that:

Wastes storage

Is no longer referenced anywhere

May be something the user wanted removed

I think media hosts like Nostr Build should push for a NIP (protocol proposal) that defines a way for hosts to:

Be notified when a note is deleted

Know which npub originally used the media

Automatically clean up unreferenced or deleted media

For example I made a draft note and uploaded this Bitcoin picture using Amethyst with media server Nostr Build but I never actually submitted the note.

`https://image. nostr. build/4798c01ec9edef36138fa9153222b7023e46349f5046b7cd1626b8810e926129.jpg`

I deleted the draft and noticed the picture is still on Nostr Builds website forever.
