The Internet makes it easier for these people to find each other, connect and share pictures and stuff, but they were doing that before the Internet. Just like it makes it easier for people with difficult lives to find each other. And romance seekers to find each other.

There are travel services for pedophiles and freaks to take sex tours around the world. The sex trade is HUGE. Women and children are forced into it, molested and raped, manipulated with threats of harm to people they love or themselves, even sold into the trade by their own parents and families. I remember one documentary where a family sold one child so they could afford to feed the others. There are married men with children among those that seek to have sex with children. They don't get proper medical care and often end up with diseases. In some places, people are misinformed about HIV and AIDS, and men with these diseases believe that they can be cured by having sex with a virgin (I'm not sure, but I think I read they believe they can pass the disease to the virgin and be cured that way), so they'll seek out a young child, because a child is more likely to be a virgin.

While the Internet makes it easier for these people to connect, I also think it lets their victims connect and make others around the world aware that they're not alone, so we can work together to stop as many of these people as we can.
