KGW (local news) and the Better Business Bureau made a fake “Office of Spam Control” and made a form, went down to PSU and offered people $5 to sign up for spam blocking. The form asked for email address, passowrd, SSN #, address, name. And it even said at the bottom “For the lure of a five dollar bill I have actually given a complete stranger my information so they can steal my identity”
The piece interviewed 4 people who gave up all of their information.
