After months of pressure from state attorneys general, Craigslist pulled its adult services listings offline over the Labor Day weekend. Visitors to the site were greeted with a black bar with the word "censored" in white text (as seen to the right) where the link to the adult services listings would normally be.

The adult services listings have been a perpetual source of concern for law enforcement, including numerous state attorneys general, who have said that listings facilitate prostitution and that children are often victimized by the ads. Craigslist originally had an Erotic Services section, but shut it down in May 2009 in response to pressure from law enforcement. The company had previously attempted to stave off criticism by verifying listings over the phone and working with the National Center for Missing and Exploited Children, but decided that having an entire section of the site devoted to the sex trade was a bad idea. Shortly after the erotic services section was yanked, it was replaced with the adult services section.

The new section, which required credit card payments for listings that were reviewed by moderators before going live, failed to mollify critics. The attorney general of Connecticut and 37 of his colleagues across the country subpoenaed the classified site over what they described as its brothel business. In late August, Kansas attorney general Steve Six called on Craigslist once again to shut down adult services, saying that the site had not done enough to fight "illegal sexual activity on the Internet."

At this time, it's not clear whether craigslist is going to get out of the adult services business altogether. The classifieds giant has remained silent so far, not offering any rationale for its move. If this does indeed mark the end of the line for the adult services section on Craigslist, it doesn't mean that all adult services ads will magically vanish; they're likely to migrate to other parts of the site. That said, the attorneys general will no doubt view the apparent shutdown of the adult services section as a victory in their war against the online sex trade.
