This site is a scam. I recently received a phone number for my new business -- a brewpub. Googling that number sent me to Stumbleupon's site (they are very good at SEO). From there the first 7 out of 8 listings were for a locksmith nearby with a totally different number.
When I called that business, they claimed to have no idea how this happened. For giggles, I entered another phone number with the same prefix, reversing the first and last numbers of the remainder. Exactly the same result.
These clowns apparently squat on unused phone #s and thereby mislead people to websites they are not interested in. Very shady.
