John...you can protect your children in your own home to a degree, but you cannot protect them if they go to someone elses home...which children frequently do..you do not know what level of security is applied to someone elses system......it is foolish to believe all parents have the same vigilance as is practised at home.
I think it is better to have to opt in...to have to use a secure pin number if you really do want to access such sites.
