Danielle's 14-year-old daughter Kristin was a healthy, happy 8th grader who ran track and got good grades. So when Kristin asked her mom for a computer, Danielle agreed. As a self-described overprotective mom, Danielle laid down some rules: No social networking sites or chats with strangers.

"She called me an overprotective mother because I always wanted to know what she was doing, where she was going, drove her everywhere she was going," Danielle says.
