Comments Authenticity is a metric that checks whether the recent comments might come from suspicious accounts or accounts that participate in Instagram Pods (Engagement Pods/Boost groups).
When checking Comments Authenticity, HypeAuditor takes into account multiple factors, among them: comment's content and the quality of an account that left that comment.
A particular comment is marked as inauthentic if several negative factors match at once.
Comments that consist of:
emojis only or words like: wow, cool, fantastic etc.
another account mentions only - comments to giveaways, contests etc.
Comments that might come from Engagement pods (comment pods, Instagram pods, boost groups) are considered inauthentic and have a negative impact on Comments Authenticity level.
Why? These Instagram users seek extra exposure within the social media space, mainly, to boost their profile activity in a non-authentic way.
