we have run into a lot of victims and a lot of advocates that call your site the walmart of child sex trafficking. in 2008 craigslist agreed to report any suspicious ads to the center for missing and exploited children which works with police to rescue trafficking victims. two years and hundreds of thousands of sketchy ads later, the center says craigslist has reported fewer than 100. >> so, the action is craigslist appears to have shut down part of what we are talking about here. but after that confrontation, after your investigation which clearly drove this whole story, has craigslist ever reached out to you and explained any more, asked any more questions? what have they said? >> i look at it as the kill the messenger effect. i think craigslist was upset that the interview didn't shed craigslist in a positive light.
