Connecticut Attorney General Richard Blumenthal LAW ’73 announced Thursday he had reached an agreement with Craigslist to crack down on prostitution ads listed on its Web site. His office took the lead in negotiating the agreement on behalf of 39 states, the District of Columbia, the U.S. Virgin Islands, Puerto Rico and Guam. Craigslist agreed to require posters of “erotic services” to list contact information and pay a fee via a valid credit card. Also joining in the agreement was the National Center for Missing and Exploited Children, which said the new requirements will make it easier to prosecute sex trafficking.
