The sad part is: It doesn't even matter what I do about privacy. I'm obviously in someone's address book. That someone wants to play some stupid game that asks for all contacts. Maybe that someone used an app like Cobook, which pulls data from their social network sites (and I'm friends with them there). In the end, they get my data, along with a picture and whatnot and I personally wasn't even involved. Heck, I could even use a dumb phone and my phone number would be all over the place. Recently, Facebook asked me once again to add a phone number "to protect my account". One time, my real phone number was prefilled in the box! They pretend that they don't have it, but since some of my friends use messenger, they surely have it somewhere in my shadow profile (a download of "all my data" obviously didn't contain it).
