you could never solve the problem of completely preventing a child or anyone from that matter from doing something if they are determined enough and you are naive in thinking so. should we remove all forms of encryption because pedophiles/terrorists use it?

if a child is determined to see naughty things online theyll just find a website that doesnt care about facial recognition laws while our privacy is still stripped away even more. So we lose more privacy as a society and kids still see what they desire just taking them a few minutes/ at most hours longer.

once again being a parent and paying attention to what your child is doing online or just talking to them about it. you choose to be a parent and that does require work to do a good job at it
