Does anybody have any idea how I could get users to validate themselves as real people, while preserving their anonymity. I had the idea they could use a credit/debit card(without a sale). Two problems there. People have more than one card. People might think I'm phishing for their details.

You can use a test prompt like an image with text that must be entered into the box. Lots of sites use this technique.

Thanks mate, but that's not what I was after.
I want my users to remain anonymous. I want to collect no personal identifying info, not even email addresses. I want to stop multiple registrations by the same person, remembering of course that many people from the same address might use one computer.
I want a person registering themselves, to be able to prove they are a real person, from a real address, but without having to provide me with any personal info.
I don't think it can be done, the best I could come up with was the credit card idea, where they would be validated by the card company but would then not purchase anything but be passed to registration.

Without collecting any specific information on someone, you can't exactly prevent one person from registering more than once. You would have no information to check against.
