The hon. Gentleman makes a good point, and that is part of the work that the UK Council for Child Internet Safety is doing with companies that want to be responsible.
Fundamentally, this is a behavioural point, and what we need is education. Right now, there is no technology that can protect our children against this sort of thing. Parental education and the education of children are both part of the mix. I look with interest at today’s motion as a consultation is under way, and we need to see the results before finally deciding what should be in the curriculum.
