Anyway, I presume this is a US thing, this would never happen in the EU, it would go to the european court of human rights (or some court or other) so fast you won't even have time to apply lube!
I imagine that with the username/password, they'd notice that it was created two weeks ago, and that your friend network is all bots.
Why not add in some of your real friends? I said nothing about bots. Tell them why you need this. Change the name of your real account to something else. Hide it. Disable it.
I think also that the new facebook timeline allows you to place "stories" and "events" to any point of time in the past.
Or start deleting what you want hidden from your facebook account and then hand over the details.
Or, how about some foresight. I don't know, how about I create a second account and keep that running side by side right now, because I'm in one of those industries that are douches about this kind of thing. I know some people that do this to keep stuff hidden from family members.
Man, I have to think of everything round here... :)
Everything I've just said I think is extremely wrong and if an employer asked me for these then I'd tell them to go fk themselves.
