Without knowing much about this. Because I don't follow any of these girls socials. I would say this a classic example of a girl suddenly not liking that the only people following her are guys. There was another girl who recently asked all her male followers what she could do to get more female followers. Saying, after posting nothing but bikini try on vids, she wanted to appeal more to females. And was tired of having nothing but guys following her.
Problem with all this is that I don't think your average girl is interested in following other girls who are not famous. Nor are they likely to follow girls younger then them.
