Connecticut Attorney General Richard Blumenthal says the deal will require people who post 'erotic services' ads on Craigslist to provide a working phone number and pay a fee with a valid credit card. The website will provide that information to law enforcement if subpoenaed to do so.

Craigslist has also agreed to sue 14 software and Internet companies that help people who post erotic service ads circumvent the website's defences against inappropriate content and illegal activity.

Craigslist will also begin using new search technology in an effort to help authorities find missing children and victims of human trafficking. -- AP
