Lead Generation Sites

This NYT article explains a new (to me) form of internet-based scams, Lead Generation sites:

By that, the Haggler means that there actually is a guy named Bob Strom, who is a bonded locksmith. And he owns a business, which you can visit, at 7352 15th Ave NW. This might seem too obvious to note, but it sets Mr. Strom apart from more than 90 percent of his local competitors. According to Yelp, there are — no joke — nearly 3,000 locksmiths in Seattle, though with relatively rare exceptions these operations aren’t in Seattle at all. 

They are phone banks, typically set up in far-off places, often in other countries. Call them and they’ll dispatch a locksmith. Some are legitimate, but others may all too often do shoddy work and/or charge two or three times the estimate.

That is another example of why social recommendations could be very useful.
