writes "A group of researchers from the University of California-San Diego, the University of California-Berkeley, and the Budapest University of Technology and Economics sifted through over one billion spam URLs, and continued clicking on each page until they were prompted to buy a product. Their findings? Only 45 advertising affiliates were responsible for all the trash. They then made 120 purchases; the credit companies OK'd 76 transactions. The spammers then processed 56 of the orders and sent out products for 49 of them.
Approximately 14 percent of spam transactions result in paying money for nothing? One very interesting tidbit; just three banks were responsible for 95 percent of all the authorized transactions. Azerigazbank in Azerbaijan, St Kitts & Nevis Anguilla National Bank in St Kitts &Nevis, and DnB Nord in Latvia were revealed as the primary money-men behind the spam scene."Link to Original Source
