Facebook is getting a closer look by state investigators, according to Attorney General Richard Blumenthal, who says the site is not keeping sexual predators out. Investigators are researching several cases of convicted sex offenders who registered on the social-networking site. “There is no question that Facebook is encountering some of the same problems that MySpace has posed,” Blumenthal told the New York Times. “They should be held accountable, and we intend to do so.”
