Pretty sure you are not the only person to ever say my name is "Notareal Personxxxx" in detroit. The internet is a very large place and has been around for a pretty long time at this point with billions of people entering "real" info into forms all over the world every day. If just one person did it before you, and that one persons info got collected and sold, you have the situation you are seeing.

No comment on if the service is real or whatever, just that your "test" is flawed.
