Except that solves nothing at all because it's easy to automate signing up or do it manually. (As a data point, use.perl.org had some spam a while back.)

And not even that matters much, because regardless of PageRank, someone might actually click on one of the posted links, too (which is what I was referring to with my email spam comparison).

The depressing fact to keep in mind is that spammers don't care. They won't check whether you use nofollow. Why should they? It just takes time they could spend spamming someone else. Since they're not trying to be nice in the process anyway, whether you are bothered by spam which gains them nothing is going to have exactly zero effect on their behaviour. You are just one flower on a praerie with millions waiting to be pollinated.

Which is why nofollow doesn't solve the problems of anyone except Google.
