KnujOn

Jotkut ehkä muistavat BlueFrogin (http://en.wikipedia.org/wiki/BlueFrog) joka keksi toimivan keinon roskapostia vastaan.

Tässä KnujOn (http://knujon.com/), samankaltainen systeemi. Suosittelen lämpimästi

About: KnujOn is a multi-tiered response to Internet threats, specifically email-based threats. The success of this project is based on the cooperative efforts of business, government, law enforcement, security professionals, consumers, and average citizens. Knujon is a meeting point for all parties who wish to make the Internet a safer place. This multi-purpose e-fraud tool has significantly reduced junk mail traffic to various users and on the Internet in general. As more networks begin using KnujOn spam, phishing, pharming and other threats will become issues of the past.
