I think this article has 2 sides to it.
of course it's not good for very young children to have access to porn because you don't want them to get in touch with porn. But on the other side, I don't think it smart to ban all of it online.
I think al lot of people like to watch it every now and then, and if they can't watch it, who knows what they might do to see it anyway!
what I should do is to make sure that the family computer is not a laptop and place it in a room where everyone can come whenever they want. if so you'll think twice before putting on some porn!
