Digital Media Lawyer Blog:  “At last, one of several suits by law enforcement authorities against Craigslist, over its alleged publication of ads promoting prostitution services, has reached a court decision.  The result, which appears to be driven at least in part by Craiglist’s recent actions to clean up its site, is that Craigslist has been found not liable for aiding and abetting the practice of prostitution in Chicago.  The case, Dart v. Craigslist, Inc., N. D. Ill., No. 1:09-cv-01385, was brought by the Sheriff of Cook County who alleged that Craiglist was facilitating prostitution and creating a public nuisance.”
