> Visa applicants who have never used social media will not be refused on the basis of failing to provide a social media identifier, and the form does allow the applicant to respond with "None."
Chances are they wouldn't (if you were reasonably cautious with, e.g., your phone). But if they find out you don't later they can throw you in jail and deport you. Lying to federal officers while getting a visa over something as innocuous as a social media account really doesn't seem to be worth it under basically any circumstances.
