Web Site for phone searches?

Found this site on yahoo (by accident):

http://escortphonesearch.com/

Looks like a recent creation. Tried a few numbers and results were interesting.
No info on its creator, hosting company, etc. Just a g-mail address on bottom of search pages.
So don't know if someone is bored, being nice, or up to no good.

Any thoughts?

I have ran a few numbers through that I know of and it seems to work pretty good
