Bad Links Manager

I’ve got a technical section in my blog and I want to give examples of sites that bother me and I want to make it easy for users to visit the sites but I don’t want the search engines to visit the sites from my site as this would pass PR etc.

It would be great to be able to register the link in a “Bad Links Manager” and then use special code to display the bad link. It could be either a regular link written in javascript or a site link with at 302 redirect on it.

I appreciate that it’s probably beyond the scope of most bloggers, maybe a plugin would do it?
