I?ve always had good adult content filters on our home computers (Netnanny; K9, Contentwatch, etc) but my teenagers now need laptops and wireless connectivity, which enables them to bypass this software. Are there are ISPs who offer the web with a built-in filter? I know there was a campaign earlier this year to try and make the default provision free of porn unless you ?opted in? but I now cannot find anything about it - can someone point me in the right direction? How do other parents stop their kids from watching porn on their laptops?
