When Angie Varona was 14, she posted photos of herself that she had taken for her boyfriend into a private account. The pics were suggestive — she wasn’t nude, but she was wearing just lingerie and bikinis in some of the shots.

But even though the photos were intended for her own personal use, they didn’t stay private. Varona’s account was hacked, and within months, the photos had gone viral to sites that teeter the line of kiddie porn — sites that trade pictures of young girls often taken off their Facebook pages or, like in Varona’s situation, stolen from accounts that weren’t meant to be viewed publicly.
