Doesn't sound like a surprise to me, sounds like he knew exactly what he would get and what he wanted to do with it.
Not that I am saying he shouldn't have done it, I just find the innocent kid law student thing funny (could this further his career? possibly).
Anyway, it really shouldn't be a surprise that these "social" companies are collecting huge amounts of personal information and no matter if you tell them NO or DELETE they still have it stored away.
If you truly don't want your information out to be seen then you shouldn't have it on your computer.
I hope more people open their eyes to that fact.
