Human-Powered Spam Filtering

arturs writes "A company called eProvisia started an unusal business: they filter out spam not by using complicated algorithms, but human beings... It costs around $20/year - is the war against spam over?" It's an interesting idea - the privacy concerns are big of course, but how would this stack up to, say SpamAssassin or a suite like Barracuda's Spam firewall. We tested the Barracuda device - great integration of OSS software, with a nice interface. Update: 09/20 15:12 GMT by J : Corrected price of Spam Eradicator.
