These things make me smile. I have a FB account. If my account had been part of that data leak, all anyone would get was my name. DoB, email, phone, in fact ALL data fields required are filled with dummy data. Anyone who knows me doesn't need FB to make contact with me (although it is simple). Likewise, or ALL of my FB Friends I hold a contact method (not on/within FB). If FB vanished off the face of the earth overnight, my interaction with friends would go on. The criminals end up with just a name...
Basically, folks - why bother populating accounts with real data?
