WHO IS PROVIDING INTERNET TO A CHILD
they are liable
there's no such thing as free open access internet without someone paying the bill
unless it can be demonstrated the child stole internet somehow, hacking, etc.
then the person providing the internet is liable for the child's activity
Same if you aren't going to supervise your child and they come home for hours after school and watch porn on the TV
They don't age verify to get cable TV
If you have a credit card, you are an adult
Someone is paying the bill, they are the adult, they are responsible
