Craigslist chief 'mystified' by sheriff's sex ad lawsuit

Craigslist's chief executive has fired back at an Illinois sheriff who is suing the popular website for promoting prostitution with free classified ads for "erotic services." ... Buckmaster maintains that Craigslist had "very positive communications" in 2007 with the Cook County Sheriff's Office, explaining the legality and intent of the classified-ad website's Erotic Services section. Craigslist says it has since instituted new measures to prevent the website from being used as a tool in the illegal sex trade and implemented an anti-abuse plan endorsed by attorneys general in Illinois and 39 other states.
