Although spam filtering and blocking is helpful for the end user, it doesn't stop the production of spam. KnujOn strikes spam at the source.
Unsolicited electronic material is more than just an annoyance. In 2004, Ferris Research Inc. estimated that spam costs US organizations more than US$ 10 billion dollars per year in manpower, software expenses, and lost productivity [1]. In addition, affected systems can suffer from a distributed loss of bandwidth and occasional server failures, not to mention the risk of virus infection and the dangers of phishing expeditions.
Citizens, consumers, politicians, law enforcement agencies, and security professionals come together with KnujOn [2] to expose Internet spammers. KnujOn (which is "No Junk" spelled backwards) is an online service that sorts junk mail, compiles information on spammers, and attempts to identify domain names associated with spam activity.
According to the website, KnujOn has helped shut down over 200,000 junk email sites. Law enforcement organizations use KnujOn's extensive spam database to search for illegal activities, and many corporations use KnujOn's services to protect their brands. For instance, a drug company or a bank can use KnujOn's services to chase down knock-off products and services that illegally infringe on registered trademarks. The participants who send their junk mail into KnujOn also benefit by shutting down spam sites and reducing the volume (and effectiveness) of spam on their own networks.
