The popular online classified ad service, Craigslist, has been subpoenaed by Connecticut’s attorney general over sex ads that appear in it’s listings. The attorney general says that Craigslist is not doing enough to stop prostitution online, and that the company is even profiting from the sex ads. Currently, there are 39 states looking into the matter with Connecticut taking the lead.

The company’s $36 million or more a year in earnings may result from prostitution and human trafficking, the attorney general contends. The NY Times reported in April that Craigslist’s earnings will raise 22 percent in 2010, largely from its controversial sex advertisements.

Some anti-trafficking organizations say that Craigslist remains the largest online hub for selling women against their will. This made the recent news when in April 2010, the FBI arrested 14 members of the Gambino crime family on a slew of charges that included selling the sexual services of girls ages 15 to 19 on Craigslist.
