The Polaris Project, a nonprofit organization that fights human trafficking, has posted billboards along the Interstate 95 corridor and increased the number of people working its hotline. The New Jersey attorney general began a campaign more than a year ago, and local volunteers are delivering soap with anti-trafficking tip lines printed on the packaging. A seminar sponsored by law enforcement was held this month, with more than 100 representatives from local hotels, restaurants and bars.

“Unfortunately, when you have visitors, this increases,” said Steven Fulop, the mayor of Jersey City, where the Broncos and the Seahawks are staying this week. “From everything we understand, the Super Bowl is an entirely different animal. It’s uncharted territory.”

But Rachel Lloyd, founder and chief executive of Girls Educational and Mentoring Services, a nonprofit that provides services to sexually exploited and domestically trafficked girls and young women, said the attention that the Super Bowl had drawn to sex trafficking and the overall sex industry may be overblown and actually hurt victims. There is no evidence, she said, of a significant increase with major sporting events.

“Trafficking can happen anytime, anywhere,” she said.

Lloyd’s organization operates a shelter at an undisclosed location in New York that serves over 350 girls and women.

“Do I think we’ll get a couple of extra young women that week? Probably,” Lloyd said. “But there will be more law enforcement, and if you did law enforcement like this on a Tuesday night in March, you’d get victims. It’s happening enough that if you look for it, it’s happening.”

In New York, prostitution can result in jail time of up to 90 days. But most of the women arraigned this week will enter various social service programs with ties to groups like housing and domestic violence prevention, said Courtney Bryan, project director for Midtown Community Court. “Many of these women are in immediate crisis,” she said.

Legal businesses, like Vivid Cabaret New York on West 37th Street, also claim to benefit from the game’s fan base. Shaun Kevlin, who manages Vivid and nearby Rick’s Cabaret on West 33rd Street, said he would increase his staff of 90 women at Rick’s to 130 this week to suit larger crowds.

“There’s a huge influx,” Kevlin said. “They come from Vegas, Chicago, Miami to audition to work here that week.”
