Can a registered sex offender gain access to a social media site?

In Packingham v. North Carolina (2017) 582 U.S. ___ [137 S.Ct. 1730] (Packingham), the court held unconstitutional a state criminal statute making it a felony for registered sex offenders to gain access to social media websites minors are known to use. The criminal statute defined a "social networking Web site" to include four specific criteria. The website (1) "derives revenue from ... sources related to the operation of the Web site," (2) facilitates " 'social introduction' " or " 'information exchanges' " between two or more people, (3) allows " 'users to create ... personal profiles that contain information such as the name or nickname of the user,' " and (4) provides " 'users ... mechanisms to communicate with other users, such as a message board.'
