I found this SF Gate story on Kottke's roundup of 2006's best links, and was intrigued/horrified by the headline in part 2:
A Youthful Mistake
You Mi was a typical college student, until her first credit card got her into trouble...
"Less than a year earlier, she'd been a college student in South Korea, only to be tricked into leaving her home by sex traffickers offering promises of a high-paying hostess job. Desperate for a way out of her $40,000 debt, You Mi bit. Now, she was at the end of yet another 15-hour shift of forced sex."
