Maureen Brainard Barnes got involved in Craig list prostitution through enrolling in a Modeling Site called Model Mayhem
From article;
Maureen worked as a blackjack dealer at Foxwoods, at a ShopRite, and at a gas station. Sometime in 2006, she saw a you-can-be-a-model offer on the web and sent in pictures of herself; a friend she made in the process introduced her to escorting on Craigslist. Maureen started taking weekend trips into Manhattan, telling anyone who asked that she was going on modeling gig.
As soon as she enrolled on a site called ModelMayhem.com, she received dozens of e-mails from places that purported to be modeling agencies but that, after a few clicks, turned out to mean nude modeling and sometimes working as an escort. She wasn’t thrown by seeing this. What did surprise her was the money.
Within a few months, Ms. Brainard-Barnes was making up to $2,000 a day on trips to New York City. She posted ads on Craigslist and worked out of a hotel room in Midtown for short stretches and then returned home to care for her daughter.
