Everyone is worried about how the DHS will verify that the set of social media accounts is complete and accurate. Easy. The officer will simply ask the visitor: "Are these all your accounts? Are you holding any back?" And then they will instruct the visitor not to lie. In order to ensure compliance, there will be a second officer who asks the visitor: "Did you lie to the previous officer?" That would provide a second level of security. You could, at additional expense, add a third or fourth officer. Anyone seeking security consulting, please DM me.
