That is indeed very scary.... what if a person, say "me" didn't want my whereabouts to be known for safety reasons.... I mean it even gives a "map it" option, leading people straight to our doorsteps.
Fortunately for me, everything it had on me was more than 5 years old. However, I put my 12-year-olds name in there and it popped him up where we lived 2 years ago! How in the world did they get information on a child; my child no less! His schools don't even know where he lives and we don't order anything from anyone (for security reasons).
Ah, big brother, where art thou?
