Microsoft Researching Anti-Spam Technique

Tim C writes "Microsoft's Research group are working on a technique to combat spam. Dubbed the 'Penny Black project', it involves making email senders perform a computation taking around 10 seconds, which their recipients can then check for. This delay would limit bulk emailing speeds to around 8000 a day, meaning that to spam all of those 'fresh, guaranteed 25 million addresses' would take approximately 8.5 years." We've reported on this before.

From the article:
"The payment is not made in the currency of money, but in the memory and the computer power required to work out cryptographic puzzles. "

Phew!!! For a second there I thought I was going to have to do a math problem for each email I was going to send. I woulda been fucked!
