craigslist has filed a complaint against South Carolina Attorney General Henry McMaster, seeking to enjoin him from prosecuting the site for displaying the solicitations to prostitution that sometimes appear there. The complaint cites section 230 of the Communications Decency Act, the First Amendment, and a few other laws that craigslist believes protect it from liability.
The complaint makes a pretty good case that craigslist has taken reasonable steps, working with law enforcement, to keep prostitution off the site. With that it has done its part. If prosecutors want to go after prostitution, they can use craigslist to do so. They should not attack the messenger if consenting adults are trying to exchange money for sexual services in their local areas.
