It was September 2006 when she took up her post at Little Ted’s Nursery, not far from her home, and her bubbly personality and ready smile made her popular with parents and children alike.But as her marriage began to collapse, she spent increasing amounts of time on the internet.Facebook's extensive but little-discussed technology for scanning postings and chats for criminal activity automatically flagged the conversation for employees, who read it and quickly called police.
Facebook is among the many companies that are embracing a combination of new technologies and human monitoring to thwart sex predators.
Such efforts generally start with automated screening for inappropriate language and exchanges of personal information, and extend to using the records of convicted pedophiles' online chats to teach the software what to seek out.

"The manner and speed with which they contacted us gave us the ability to respond as soon as possible," said Duncan, one of a half-dozen law enforcement officials interviewed who praised Facebook for triggering inquiries.
When Secret launched in February, it quickly became the most talked-about new social network in Silicon Valley.
Like other ‘"anonymish" social networks, it offers a compelling mix of sex, drugs, and intrigue.
But Secret goes a step further by connecting to your phone’s address book, then showing you your friends’ posts without revealing which friend said them. But in recent months, Secret has lost some of its initial power.
Several news stories broke first on Secret, fueling buzz that led the app to be downloaded more than 15 million times in 10 months. The number of posts from friends in my feed slowed to a trickle, and Secret is no longer among the top 1,500 apps, according to App Annie.
But Facebook believes this chat app has a place in that already busy lineup. It also was designed for mobile devices -- a departure from cramming Facebook's website features into a small program that fits on a screen nestled in the palm of your hand.
