Persons convicted of sex offenses in New York do not have to specifically disclose to the state that they have, and use, an account on Facebook, so long as they register their email address and don’t use a fake name, the state’s highest court ruled Thursday.

The decision, which was unanimous, will allow an indictment against a Ticonderoga man, who did not disclose to the state that he used the social networking website, to be dismissed.
