Facebook and Google both do their own targeting (obviously.) Google allows access to some data for 3rd-party firms via RTB. Neither pass on PII (or really any non-aggregate) data to advertisers, AFAIK, I'd be surprised if Specific did either. Google and Facebook both have a consumer-facing presence so you think of them as being more accountable, but they're both advertising businesses, no doubt.
