I don't know about that. There was a legitimate research report from a while ago that found that the sudden spike in this kind of behavior seemed to come from peer groups in teen girls. I think that the underlying behavior to step outside of societal norms or bounds exists, but the way in which in manifests changes over time. I recall when I was younger there was a similar degree of worry over teenage girls getting involved in witchcraft because that had reached some level of cultural awareness and popularity.Most kids have this same access and most aren't trooning out. The people that troon out are already disturbed.
The main difference is that teenage girls playing with Ouija boards or doing stiff as a feather light as a board in their rooms at sleepovers were far less likely to inflict longterm damage as the people toying around with this shit. I think that eventually this will die down, because the next generation will embrace something else instead of this idiocy, but there's going to be a lot of longterm suffering and remorse over this shit. As the saying goes, if you can't be a good example, you can always serve as a horrible warning.
