Craigslist took down Adult Services in the U. Advocates seized on the ambiguous move today, calling on Craigslist to remove the infamous section in cities across the world. Post-censorship, ads for sex are migrating to other classifieds sites and other sections of Craigslist. Profit is a powerful motivator and the fact that Craigslist makes so much money off these ads undermines its moral authority [UPDATE: A reader points out that Craigslist started charging for these ads after negotiations with attorneys general and National Center for Missing and Exploited Children, so that credit card information could be kept on file. But is ending that revenue stream a worthy pursuit, given the strong arguments that Craigslist does more good than harm by making it easy for law enforcement to find and track sex traffickers, and empowering prostitutes to escape often-abusive middlemen? Singapore, where the Internet is censored for porn, is the only Craigslist site without an Adult Services section.
