blocklists on nostr are admittedly somewhat less of a problem than on the Fediverse because if a blocklist blocks a single person it doesn't also take out a thousand other innocent users like a server blocklist does on the Feiverse. But I am going to predict the future for you. Eventually blocking individuals is not going to be enough. Someone is going to scrape every nostr.json. They are going to make lists of what relays the bad person uses and they are going to add everyone using that relay to a list. maybe they will give the relay a chance to drop posts by that person, or maybe they will just do it,
