I understand this is unpopular on HN and I don't think this is the right approach either but what is the solution? Or do you think there's no problem at all? I think it is a potential problem where some young people don't realize that some fairly disgusting and extreme sex acts are not the norm and start dating thinking that is what you do instead of loving someone, that would cause them serious issues in developing…
That does leave open the possibility that some children would be exposed to "extreme sex acts", and this would probably disproportionately affect the poor.
The government providing free voluntary filtering software would probably irk people less than the government policing morals.
