I'm interested to know: do you have any children, and if so, what age? Not that that is the end-all-be-all of knowing how to parent, but comments like "explaining what is right and wrong, he is very unlikely to develop any interest towards 'bad websites'" make me think that you don't have much experience trying to raise children. They test boundaries. They misunderstand morals of stories. They have primal urges. They disregard social customs that they see as irrelevant. I'm constantly explaining right and wrong to my children and they are probably slowly getting it, but it's a process.
