What you're describing isn't a cancer to children but a danger to _people_, children or not. Children being children, they're sometimes less able to recognize danger ahead of time, and they're also more likely to get their kicks from sending each other there (I know I did). This is also not inherent to the Internet, however. "Stranger danger" warning exists for a reason. What we need to do is teach children that just like you wouldn't follow a random stranger into their house, you also shouldn't click random links. You also have to make the safe place dedicated for kids into a place that they actually _want_ to be (think neopets in the 00s), and then you don't have to put your resources into preventing them from leaving.
