There are lots of stats out there about spam. According to a study from Richi Jennings ((Jennings, Richi, “Spam and Other Email Threats: Market and Technology Update.” Farris Research. 8 Jun 2007. Ferris Research. 9 Jun 2007 .)) , Spam cost the world $50 billion in 2005, the U.S. about $19 billion. Projects are that for 2007, that number will double with $35 billion costs for the U.S.
To put this into perspective, acording the to Copenhagen Consensus ((Kerr, Roger. “hard-Hedadad Spending Decisions not Cold-Hearted.” BusinessROUNDTABLE. 2 Jul 2004. New Zealand Business Roundtable. 9 Jun 2007)) , we could bring HIV Aids, world wide, under control for only $27 billion, less than we’ll spend protecting ourselves from spam.
