TOPEKA, Kan. (AP) – Kansas Attorney General Steve Six has joined 16 other states’ attorneys general in asking Craigslist to drop its adult services section.

The attorneys general on Tuesday announced that they have sent a letter to Craigslist CEO Jim Buckmaster and founder Craig Newmark that contends that Craigslist has not kept a pledge to crack down on illegal sexual activity on the Internet.

Six says that since the 2008 agreement, Craigslist has done little to eliminate advertisements for prostitution or even trafficking of children.

Other states represented on the letter are Connecticut, Arkansas, Idaho, Illinois, Iowa, Maryland, Michigan, Missouri, Montana, New Hampshire, Ohio, Rhode Island, South Carolina, Tennessee, Texas, Virginia.
