AutoFollowToolVisible lists are not always complete
A source can be partial even when it returns valid people. A missing page, interrupted cursor, and a truly empty population must be represented differently.
Missing versus confirmed non-follower
Confirmed non-follower means the follow-back field is known false. Not finding a username in a truncated followers list leaves the relationship uncertain.
How previews show uncertainty
A useful preview shows unknown and excluded counts beside eligible candidates. It must not relabel unreadable attributes or stale relationships as confirmed matches.
What to do before unfollowing
Before an unfollow, refresh relationship evidence within the configured policy and keep exceptions protected. The policy’s evidence lifetime is not an Instagram guarantee.
