I’ve written in the past about funny/stupid spam e-mails I’ve received, but the amount of spam anyone gets who is even moderately active on the internet isn’t particularly funny. I’ve just started using something called SpamNet, which collects information about spam e-mail sent to all its users to block future e-mails. When you get a spam e-mail that the system didn’t already block, you click on “block,” and that e-mail is blocked from all users of the system. It’s a cool use of collaboration over the internet to help stamp out spam. That’s a good thing.
The problem with any anti-spam measures is you still have to look over the blocked e-mails to make sure no legitimate ones were flagged incorrectly. So I don’t know how much time you save. But it’s just nice to have those messages moved out of your inbox in the first place.
