do these zips represent what fb makes available to advertisers/app publishers/partners/researchers or is it just a dump of everything fb has on you as a user? seems there's at least a few different ways for your info to leak... what exactly is provided to an advertiser? what exactly is provided to an app publisher, assuming the user granted permissions to access the phone & contacts? certainly personally identifiable info in the 2nd case. is there no safeguard against 1 idiot contact sharing YOUR info without YOUR consent?
