I don't care for black hats... but I can't say Ballz' suggestion is a bad one or anything. But what are you doing looking for this on the darknet? This is big business these days. Facebook, Google, Yahoo, any convenience store with one of those stupid savings cards -- this is what they do. They profile customers for targeted ads. It raises the click-through rate by a substantial number, so it's worth paying for.There's gotta be somebody you can buy this info from legally and without the damn hassle of people trying to scam you for your bitcoins?
