I don't think so. The story here is "horrible things happen to underage girls who hang out on Instagram". So I don't need to be a doctor to evaluate "horrible things". Either horrible things happen, or not.
In the real world, what if somebody would be beaten up in a certain part of town, every time they go there, and they keep returning. You wouldn't have to be a doctor to ask "why does he keep returning".

No but you need to have domain expertise to understand the mental and emotional processes that lead to decisions being made, especially by people whose brains are still developing.
You'd have to ask a psychologist, but I'm sure the dopamine hit that comes from all the attention plays a role.
