I’m convinced that some of those comments are from ‘Paid’ followers. If their comment section is filled with nothing but praise, it gives off the impression that they are a popular and likeable family, to the average person whom the algorithm suggests the posts to. This then prompts the average person to think they are likeable, and therefore they start following them as if it’s a trend. I believe it’s the same for all their social media accounts.. That’s how all these families get popular almost over night. The secrets of social media.
