On a tangential note, slightly less than 20 years ago I got a phone call from an ex of a girl I was seeing at the time telling me to back off. All he had to go on was my name and what college I went to. I asked him how he got my number, he said he used a service like you're describing. This has never been particularly hard for someone who was determined.
