So to me the whole thing simply doesn't make sense, who actually did buy something from an ad?
The only signal I value for trying out (buying) new things comes from real people.
The privacy implications of storing so much personal data is the other question and that can be used for some bad things that isn't just serving ads. Would be nice to have a law for mandatary differential privacy for ad based social networks.

Perhaps I am losing out on ignoring all ads wholesale like that. I even sometimes put products that do 'a lot' of advertising in bad light and try to avoid them all together.
