Mute just keeps you from seeing their notes, block prevents them from seeing yours, maybe 😜

Only option I see is Mute User. I think that the this premise behind NOSTR, you can’t censor anyone but can choose not to see their activity by muting them. I think they will be able to see your activity, but you won’t see their responses if they try to comment on your note. You will get a notification that someone you muted has commented, but you won’t see what they said. 🤙🏻
