Spam is still a problem, but its becoming increasingly centralized — which could make its eradication that much more easier if those battling it play their cards right. Research firm MessageLabs reported Monday that 83.2 percent of all spam originates from Botnets.

MessageLabs has put a list together of the biggest spammers, and found the biggest target is “Cutwail,” which contributes 45% of all spam. Shutting down a network like that would obviously diminish considerably the amount of spam being sent out.
