It looks like Craigslist is in the process of pulling the 'Adult Services' classified ads from their site. I saw a couple of stories this week about a coalition of State Attorneys General who were trying to clean up Craigslist. Now there's a CENSORED band over the Adult icon and they've disabled the thread.
I knew that 'Craigslist Killer' story was the beginning of the end. Oh well, its not like there aren't dozens of other sources to turn to.
