I don't think the dispute is whether there should be open ads for illegal activity. The proper course is to settle that between law enforcement and the offending party, not law enforcement and the medium, especially when doing the latter means stepping on the free speech of some people posting legal ads. Some people choose to drive while intoxicated, but nobody's demanding we take down the roads, or calling local governments accomplices to illegal activity (nor car or alcohol manufacturers). There are plenty of sites on the Internet where one can engage in illegal activities. The question is why this one? And why this activity?
