I honestly think this part here is the problem. They get in touch with each other, start sharing stories, what worked for them, and eventually you end up with clones of clones of clones.
Instead of being their own individual, herd mentality kicks in and we get those garbage botched implants on every single one of them. Remember the era when every girl was trying to be a Belle Delphine? Or the more recent trend, in which every girl is somehow a gamer (or at least they have a "gaming" setup in their rooms)?
