Paul, I once worked as a telemarketer. One way they gathered information was to place boxes and forms at fairs, in malls and lots of places where there would be lots of people. The sign usually advertised winning a truck or car or trip to Disney or a weekend at Foxwoods. The drawing date would be far enough off that people would forget about it or figure that they did not win. The form asked for the usual name address and telephone. On the back of the form (few ever looked there) was a blurb that said something to the effect that by signing this you are giving permission for our agent to call...blah.. blah.. blah. Then the forms went to the call center where the agents would call and try to sell the time shares. Of course no one ever won the "drawing". So be careful what you sign up for at malls, check the back of the form, you might be releasing your info to telemarketers.
