A pretty grid is not an audience. Small brands get burned by accounts that look active and convert nobody. You do not need a $400/month spy tool to catch the obvious fakes. You need a checklist and the nerve to skip a cheap account.
Follower-to-like ratio is a start. It is not an analysis. Bought likes can look healthy. Story views, Reel views, saves, and whether comments mention the product are harder to fake at scale.
We do not forecast “views on a pinned comment.” Instagram does not publish that number. We estimate Story viewers from the creator’s own history, then estimate taps from a stated rate, and we label it as a model.
The honest line in a DM is: send the view counts on your last five Stories and the top countries. Creators who are real send a screenshot. Creators who are performing a media kit send a speech.
