I tried fixing the links in Iamcuriousblue's comment itself but couldn't get the system to let me save the edited version, I think because IACB wasn't logged in when he made the comment. (I kept being asked for a "valid author." So, IACB, if you get back here and feel like registering, that'd be really cool. We'd love to have you on board anyway!)
Meanwhile, here are the links to the sources and resources he mentioned:
Global Alliance Against Traffic in Women and their report "Trafficking: A Demand Led Problem?" ("excellent overview of the multifaceted nature of the sex industry and the relationship of sex trafficking to parts of that industry")
Coalition Against Trafficking in Women, NGO that takes an prohibitionist position on prostitution and supports US funding policies tha deny aid to any organization, even outside the US, that does not actively oppose prostitution.
The Mother Jones article that gives lots of good info on the US aid policies, and the issue of trafficking "Sex Trafficking: Zero Tolerance".
La Strada Association, "one of the main groups doing actual work on the ground in Eastern Europe trying to help trafficked women there."
I'll add the organizations mentioned to our links page. I need to create a category for reports and studies, I think!
...because public space really matters!
