It's two decades old, but so is the stuff on his site. Go look at Shields Up - it's all written like people are still plugging their computers directly into their DSL modems and cablemodems. I couldn't find a single acknowledgement that his service isn't necessary for 99% of users on the internet who are behind a NAT router. Nor does he acknowledge that most ISP's have long since adopted policies of blocking traffic on common windows network service port numbers. Anyone behind a NAT router doesn't need to worry about any of this unless they've modified its configuration to forward some ports. He's also now hawking spinrite for people with SSDs, claiming it helps their reliability. It's complete nonsense.
