I looked up both my wife and myself there. It would seem that most of the information there is public record info anyway, just packaged into one quick search. I may be off on that, but I didn't see anything about SSNs showing up in those searches. Certainly not in the free one, and nothing is mentioned in any of the premium choices.

I have, however, seen SSNs show up in recorded mortgages. Now THAT's scary!
