Why spam isn't going away soon
(Hint: Blame the Storm worm)

Recently, Symantec said in its February 2008 State of Spam report that 78.5 percent of all e-mail is spam; they also said most of that is now coming from Europe. That's a change from previous reports that had suggested servers in North America were responsible. What the Symantec report doesn't explicitly state is that much of the European spam doesn't come from individuals sitting at their desks pumping out lists. Europe is one of the hotbeds for the Storm worm botnet, notorious for automatically co-opting its victims into spam relays.
