I can only answer with what I’d expect: - Block has no meaning on Nostr because you can’t - Mute means I don’t see that person anymore - Ignore could mean I don’t get notifications, but they still appear.

Ignore = don’t show them in the feed, but notify me if they tag me or reply to me etc. basically “i want to see less of this person” Mute = any events at all from this person should be filtered out. Block = don’t allow this person to see my posts. not possible on Nostr today, BUT when we have private posts, this is an easy solve
