The study relies on data collected between 20, including interviews with teenage Internet users as well as federal, state and local law enforcement officials.
"Between June and October 2007, we conducted over 400 interviews with police about Internet-related sex crimes and we have yet to find cases of sex offenders stalking and abducting minors on the basis of information posted on social networking sites," report authors said.
That pattern "may be changing," however, as different technologies emerge, the study said.
Our involvement with the industry continues to this day.
My Space made its debut in February 1999, while Facebook was made available to college students in February 2004 and to the general public in September 2006.
Kids with social networking sites are "no more likely than other youths online to have uncomfortable or scary contacts with unknown people," the report said.
Researchers did find, however, that a majority of predators who convinced their victims to meet in person did not resort to violence or abduct the children.
Most are "patient enough to develop relationships with victims and savvy enough to move those relationships forward," the report said.
Kids who spoke to unknown people online, had unfamiliar people on their buddy lists, freely talked about sex with strangers online, looked for pornographic material on the Internet, or who were routinely "rude or nasty" while online were found to be at greater risk.
