There are fewer pedophiles per capita and they're getting caught sooner and sooner. I'm not saying abandon all safety precautions, just don't worry yourself crazy over it.
I'm not sure where you're getting that concept, would love it if it were true but it's just not. The percentage of pedophiles pretty much remains constant.
The pedophiles are still all out there and they're just getting better at fooling the rest of the world. In my life I have personally met and associated with more than five of the filfthy horrid creatures (sorry really have trouble thinking of them as people - call me descriminatory if you like) seen two put behind bars and three get away with it despite much evidence (usually parents not wanting to put their children through court - a topic for another discussion but so not the right way to handle it).
We must always be extra vigilant, trust no one and ensure that the right relationship tools with our children are in place. It is much harder for them to victimize a child who has a good relationship with their parents, in fact most of them wouldn't bother trying with such a child. You cannot be with your child every moment but they can know that they can come to you with any thing, they can know what it is right and what is wrong, you can be extra vigilant in constantly re checking the people in your child's life and environment and always having open conversations with your child about their feelings.
Sorry to carry on but I have seen so much of this and so many people think it doesn't happen much because no one wants to talk about it once it has happened you hide it away and everyone carries on thinking the world is a nice place. The number of children who are exposed to this in varying degrees each year is even worse than the "known statistics" which are around 15%-25% of girls and 5%-15% of boys. Put a hundred kids in a room and as many as twenty five of them could be victims.
Children should not be on the internet by themselves, teenagers should be constantly monitored (they have to have some chance to learn independence after all) and it should never be a hush hush topic.
I wonder if the advertisers on this sick heads' site are aware of his activites - I highly doubt it!
