I have plenty of (pretty much inactive) social media accounts that I don't even remember the user-handle or password to -- usually created to take look at the service, user-interface and goof around a bit -- I don't think I'll ever remember any of these (also, they were usually created with throwaway-email accounts). I don't plan to travel to the US -- pretty much because of the reasons outlined here. But if I were I'd pretty much either had to lie or tell them that I don't remember any of my logins -- since I had them at one time, but I don't have any active social media presence anymore. And what about github, stackoverflow, hn... are they social media -- I don't think so. But not mentioning other accounts that could be classified as social media is also a lie -- at least its an omission.
