Right but then why bother with the grey-list then? Just whitelist or don't share the notes I guess. No one is going to check if their notes are propagating on relays, they just hit send and hope they get reach, but sitting in a greylist you'd just sit there wondering why your note never got reach. Grey-list meaning it requires manual human intervention, otherwise it's still just a whitelist/blacklist with spam-filters. How many relay operators will be minute-level attentive for social feeds? We both know that nostr is highly time based right now. There are all kinds of dates and times that are optimal to get even just your closer friends to see your notes.
