All accounts should be marked with the degree at which they are followed. Users should immediately see the difference between a direct follow and a 4th degree follow or an out-group account. If your follows reply to an out-group note, that note should be shown as part of the thread that made it into the user's feed.

Replies to in-group notes should only be shown if in-group accounts replied (referenced) them with any of their events. Therefore we should never need to query nostr for "#e":[<eventId>] like other clients do. I suspect they will quickly get mostly spam that way.

I don't care about how many out-group profiles liked or replied to an event. It's so gameable, it's just irrelevant.
