The OP mentioned that Facebook is a big corporation so they clearly must have secure data structures and invincibility from all attacks ever. I'm just pointing out that to support my point -- Facebook has the ability to fetch the data but really doesn't want to. Secure data structures have nothing to do with it, they don't prevent the fetching of data. And if Facebook is smart, they don't just throw things around randomly in the database without rhyme or reason.
What? No one said anything about invincibility from attack, or security in general. And the point was that they have a complex infrastructure, not that they throw things around randomly without rhyme or reason.
