Internet safety experts say parents know some of the dangers but assume it's not happening to their kids. They might be wrong.
"I would just caution parents that online problems can be just as big and important and consequential as offline problems," says Stanley Holditch of InternetSafety.com.
Holditch tells parents to ask their kids for a tour of their favorite websites and friends online. Then parents should create their own accounts, as if they were children of that age, to see what their kids experience online.
The message is part of his job. InternetSafety.com is a subscription service that tries to stop children from venturing into cyberspace's bad neighborhoods. But he's as passionate about teaching parents what's out there and how to keep their children away from the worst of it, he said.
