deletions on nostr are expensive for clients and relays that need to keep track of what has been deleted. relays are forced to keep a table of all these deletion notes and query against them for every inbound event to make sure they're not accepting events that were deleted a long time ago that just resurfaced now. this will never scale well and no relay / client should opt into this theater. IMO it only works now at a small scale, but as the network grows it will be unsustainable for any relay and client as the list of deleted events only grows.
