Excellent topic. Many factors to consider.

One of the main ones being parents giving their 5 year old an iPod, mobile, pc...etc.

I don't believe in filtering. It happens here but for acceptable reasons..or so I shall state here.

Parents should monitor and limit a childs freedom.

It's not the internet that's ruining your kids. It's you!

Your 12 year old doesn't need a smart phone and a full time internet connection.

People should stop blaming the internet. Many of us here have been using it for a considerable amount of time but we didn't turn out to be rapists or sex freaks.

You should teach your kids values. After all the sites in topic don't open themselves and take you kids to them. For such access the childs initiative too is required.
