the larger conversation, as i just mentioned, which you were not involved in at the start and obviously did not bother to be sure you understood is this conversation is about deleting at the protocol level. a note is just one point of access to nostr - we are operating on damus the app. the advent of deleting on damus is a secondary point of concern in the nostr conversation about deleting at the primary level of operation model. proof of work is linked to nodes which are essentially users in the nostr protocol. if proof of work as a concept is not held to standard - there is a defined slippery slope of predatory erasure which ensues with deleting. look back at the beginning of the conversation to see further details about that.
