Do they have SSN?
They claim that they have SSN but that seem to be lie because of following reason. When I searched for my name, they showed two results with different postal address, and both address were correct, I have lived at those addresses; my point is if they were to have my SSN, they would have linked those two results in to one. I am almost tempted to buy my personal results and see what they have.
