Each check takes a random sample of 150 Instagram followers for a user and calculates a score for each follower. This score is based on profile completeness and ratio of followers to followed. We use these scores to determine whether any given user is real or fake. Of course, this scoring method is not perfect but it is a good way to tell if someone with lots of followers is likely to have increased their follower count by inorganic, fraudulent, or dishonest means.
FollowerCheck is not affiliated with Instagram in any way.
