It’s an awesome little program by a company I thought of applying to out in Silicon Valley. They’re a small batch of smart entrepreneurs who came up with a viral solution for stopping spam. You join their community and get an Ebay-like rating based on the number of actual spams correctly blocked and every non-spam correctly unblocked. A high rating gives each user a higher weighting in their future determinations of an email being or not. It gives no weight to people who report everything incorrectly as spam. That means that as soon as a handful of people report something as spam, those emails never hit the rest of us. Spam email signatures get blocked in minutes once the number of users hits a certain number of thousands, which was hit at least a year ago.
Give the 15-day trial a try. You install in minutes, see one or two pop-ups about how it works when you next open Outlook, and then you see a new folder called “Spam” fill up with new emails that you never have to read (unless Norton pops-up annoyingly that a virus email has been quarantined). Hardly any spam, and when you do your job to block or unblock, you help the process, and you get recognized with a higher rating. Gold star. Pat on the back. The people that buy or click on spam links should lined up and kicked in the balls. Don’t even know what I would do if I met a spam sender in person.
