Second, the Internet allows access to the world and therefore a pedophile can pray on a victim that lives 1000 miles away just as easily as if the intended victim were next door. Technology virtually obliterates geographic distance. A cyberpredator can in fact be more alluring for a disenchanted youth by offering a plane ticket to some exotic location. The enticement of being independent might cause some naive adolescents to travel to meet the cyberpredator, or the cyberpredator can also arrange to fly long distances to meet the intended victim in person.

Third, technology enables long-term and intimate communications that would otherwise not be possible. It would be far more difficult to "groom" children without the Internet except when the pedophile is a member of that child's family or immediate social network without attracting attention. Online grooming can take place over a long period...

This trust-building would not be as possible to establish with a stranger living in the community.
Fourth, technology makes pedophilia easier because it is difficult for parents to thoroughly monitor the child's online communications or mobile phone communications. those communications do not always take place in the home and can easily take place in a cybercafe, for example. Another reason why technology has made it easier for predators to attract victims is that a cyberpredator can easily initiate cellular phone or SMS (text messaging) conversations with youth without the parent knowing and without the child having to tell his or her friends.
