Facebook Will Reveal Who Uploaded Your Contact Info For Ad Targeting

In March, TechCrunch discovered Facebook planned to require advertisers pledge that they had permission to upload someone's phone number or email address for ad targeting. That tool debuted in June, though there was no verification process and Facebook just took businesses at their word despite the financial incentive to lie. In November, Facebook launched a way for ad agencies and marketing tech developers to specify who they were buying promotions 'on behalf of.' Soon that information will finally be revealed to users. From the report: Starting February 28th, Facebook's 'Why am I seeing this?' button in the drop-down menu of feed posts will reveal more than the brand who paid for the ad, some biographical details they targeted, and if they'd uploaded your contact info. Facebook will start to show when your contact info was uploaded, if it was by the brand or one of their agency/developer partners, and when access was shared between partners. A Facebook spokesperson tells me the goal to keep giving people a better understanding of how advertisers use their information.

This new level of transparency could help users pinpoint what caused a brand to get ahold of their contact info. That might help them to change their behavior to stay more private. The system could also help Facebook zero in on agencies or partners who are constantly uploading contact info and might not have attained it legitimately. Apparently seeking not to dredge up old privacy problems, Facebook didn't publish a blog post about the change but simply announced it in a Facebook post to the Facebook Advertiser Hub Page.
