how do you stop them if they use a computer out of the house, any type of tablet, mobile phone that can access the internet. I mentioned this before, i came across a porn site just by accident, sounds funny, it wasn't, i typed in something i was looking up and there were these vile pictures of a girl, i wouldn't have put her age more than twelve, she could have been older, but if i can do this by accident, so could a child or if a bit older by design, they are far more proficient and know what to look for.
