McAfee has finally released the results of its S.P.A.M. (Spammed Persistently All Month) experiment, which began in March. The project: take 50 people from ten countries to defy common sense and for 30 days surf the Web on a computer with no anti-spam software. Not just that, they were to take risks, and respond to spam, to make matters worse.  The results were unsurprising. Of course, being the security company that it is, and having its own anti-spam product, McAfee has a vested interest in the results.
