Anyone running a site that has user-to-user interactions has to provide risk-assessments for each of:
* CSAM;
* Grooming;
* Terrorism;
* Under-age access to porn;
* Modern slavery;
... and more.
For each of the above there must be written policies about how the limitations are enforced, and the procedures taken for each of the risks identified.
I've download some, but not all, of the explanatory and guidance documentation and it amounts to around 1100 pages of legalese so far.
My observation has been that as long as basic human needs are easily obtained there is a natural tendency to become complacent and go with the flow.
Another perspective could be: what’s so bad about people taking longer to mature? In a way it points to the possibility that we have evolved to a society that allows children to be children for longer. The real problem is that biologically their bodies are screaming for reproduction which becomes confusing and stressful. Perhaps in the future we will deal with this in creative and healthy new ways
