"Four Terre des Hommes Netherlands researchers spent 10 weeks posing as prepubertal Filipino girls on 19 public chat rooms. During that short period, a total of 20,172 predators from 71 countries committed crimes by soliciting the Webcam child sex tourism (WCST) research researchers, whom the predat ... ors believed to be minors, for paid webcam sex performances. But 20,172 crimes in a sample of 19 chat rooms likely reflects only a small fraction of the number of crimes actually taking place every day when we consider the US Federal Bureau of Investigation’s estimates that there are 40,000 online chat rooms on which predators lurk. Moreover, WCST takes place on social networking sites, adult webcam sites and online dating sites, in addition to chat rooms. It is likely that WCST takes place tens of thousands of times each day.

The finding that WCST is such a common crime on public chat rooms led us to investigate whether law enforcement agencies are not adequately enforcing existing child protection laws because they are unable to identify predators engaging in WCST. We found that identifying predators seeking webcam sexual performances from children can be achieved through the use of a proactive investigation technique. During the 10 weeks spent collecting data, the four Terre des Hommes Netherlands researchers identified 1,000 predators seeking webcam sex performance from children on public chat rooms. They were identified using only information available in public online databases and data provided by predators. No computer hacking or illegal methods were applied. Instead, we just asked predators to provide identifying information under the fictional pretext—a technique known as “social hacking." (Executive summary, page 4-5) more
