I have been very conflicted on this, I guess it's worth reconsidering the idea of nip-09 == privacy. I personally would (and still intend to) manage a note archive for permanent history, ignoring any deletes of course. I suppose this would likely only relate to kind01, however if I was a pita I would also hoover nip46 traffic and other npub identifying traffic to prove a point. The world is full of malicious people, and I firmly believe once you touch your keyboard you are voluntarily producing information that could be of value to a bad actor. I don't want computing systems to function this way, but the reality is they do.
to also reply to nostr:npub1njst6azswskk5gp3ns8r6nr8nj0qg65acu8gaa2u9yz7yszjxs9s6k7fqx point on "Good Enough deletion to stop an opportunistic bad actor" it only requires someone like me to stand-up an archival service and all it takes is someone to search a profile to supply these "opportunistic bad actors". In fact one could argue this is worse as deletion events could also be recorded and shown that user's attempted to hide/edit notes. I'm simply stating this is too easily combated and will always be the case when content is distributed, period. We cannot force people who believe in permanent history to respect your pseudo-privacy.
