If someone is giving you fake info, it's because they don't want to be contacted. It's a cold lead you'll just spend money chasing that most likely will never convert.
I'd rather buy from someone who is actually willing to listen to me.
The comprehensive history, by contrast, is really starting to creep people out.

The claim that Google requires intrusive personal dossiers for revenue generation is a myth. Google doesn't even use detailed personal dossiers in search ads, which we all know generates the vast majority of Google's revenue. It's really hard to do much better in search advertising than current query + location. Yes, we do a bit more than that, and will probably do more personalization going forward, but more personalization rarely yields more revenue. Instead, it usually improves our metrics associated with user satisfaction, although again the effects are probably far smaller than you would think.

I don't really know what this means for you. I'd be interested to hear from anyone who has some idea.
