NEW YORK - Authorities say more than 3,500 registered sex offenders were kicked off social networking Web sites after a state law required them to register their e-mail addresses.

The state Electronic Securing and Targeting of Online Predators Act (E-STOP), which was signed in 2008, requires sex crime convicts in New York to register their physical and e-mail addresses. Both Facebook and MySpace ban sex offenders from using their sites.

Attorney General Andrew Cuomo says the high number of sex offenders removed from the sites shows the law is working. Cuomo wants other social networking Web sites to participate.
