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.

To refresh your memory, a botnet is a group of computers running distributed software to perform tasks such as sending spam or distributing malware. Using botnets for spam could be blamed for the marked increase in spam itself: it now accounts for over 90 percent of all e-mail.
