Microsoft: "magic" spam solution overhyped

Microsoft: "magic" spam solution overhyped. No I will not pay to send e-mail. I am already paying that fee to my ISP each month for my internet access. And a "computational challenge" system sounds like it could work but make sure there are no holes in the system before it is rolled out. All I can see is this allowing more spam to come through and put the legitimate people on a black list. That and I see a new series of viruses come out of this to attack these systems.
