I know of at least one state (Indiana) that banned RSOs from social media, but that statute was ultimately struck down by the Seventh Circuit Court of Appeals. Basically, the court said that RSOs who have served their time and are not on conditional release, have every right to be on social media. Thus I don’t see the NC issue having anything but a favorable outcome.
Something I would like to see challenged is the requirement for RSOs to provide their “online identifiers” as part of their registration. I know that California’s Prop 35 was struck down in this regard, and I believe Illinois’ as well. I have a boatload of “online identifiers” that takes up a couple of pages; it drives them crazy.
