I'd like to see an employer, or whoever personally oversees applicants, deal with the response "Violates contract with Facebook to share information. Go to them for it." even if they don't have to do much to convince the Supreme Overlords of Facebook to fork over the info. Maybe add in other laws or legal cases where privacy was protected as a round about way of saying SCREW YOU!!! Personally, I'd take the sheet to whoever is overseeing applications and ask why they expect me to break an agreement with one entity just for them and not leave until given a damn good answer.
The funny thing is that I know one person who has about half a dozen FB accounts just to play those stupid games. Free daily gifts that you definitely need, having more 'Villes to play with, and less hassling other people to pitch in. What's to stop them from having an account just for employers to see? After all, all those "friends" with the same last name and similar pictures could easily just be family members with a stunning degree of similarity in everything.
Now I did give my phone number to my doctors because they may find something in one of their tests that should be dealt with NOW rather than in a few weeks. Not to mention reminders when an appointment is coming up soon so I can get out of anything else that may pop up for that same time. They know better than to call just to see how I feel because I'll definitely be calling them if anything feels wrong. Stores, however, have no good reason to have my contact info when I leave the building.
