Facebook will reveal who uploaded your contact info for ad targeting
I just counted and Facebook tells me that 1,147 advertisers have uploaded a contact list that contained my info, specifically found on https://www.facebook.com/ads/preferences/?entry_product=ad_s... :    These advertisers are running ads using a contact list they or their partner uploaded that includes info about you. This info was collected by the advertiser or their partner. Typically this information is your email address or phone number.    

Want to know what's funny? The email address I use for Facebook was created only for Facebook. I have never given it out to anyone else, ever. The inbox for that account only contains emails from Facebook. I have never given Facebook my phone number. I have never clicked on an ad in Facebook. I have never connected an app with my Facebook account. _Facebook_ itself is the only entity which has ever had my contact info associated with my account. So tell me, how did 1,147 other businesses and groups get their hands on my info if I've never given it out? I can't wait to see what the explanation is when this feature launches end of the month.
