I fall into a 3rd category: I used to log into FB once a month or so to check in. For some reason, they decided I was a fake account (despite working for them for 4.5 years) and asked for my ID. The resolution on my 10-year-old MBP was too low for FB's contractors so they rejected my ID 3 times and I seem to now be locked out of my account indefinitely.
Definitely in the top 10 best thing to ever happen to me.
