Good question. I've seen 1-2 other people wondering about this. The short answer is that we'll make sure the rel="nofollow" takes precedence. Otherwise spammers could exploit this.
Thanks for your reply Martin. However, my question is if what Chris Hunt said was true "having two rel= attributes might cause G to ignore the second one", would Google treat the link as a normal link or a nofollow link?
What I really want to know is whether spammers can use this technique to bypass the ref="nofollow" attribute.
Multiple occurences of the same attribute are treated as if the values specified were in a single attribute. However since there is no "follow" value defined for the rel attribute it won't have any effect.

Only (potentially) if they're able to insert HTML into your page, which they really shouldn't be able to do. I'm guessing that your blog has a place for people to enter a URL, and some devious individual has put this one:
I haven't tested this in a while but a couple of months ago, when you apended rel="follow" before a "nofollow", the link would pass pagerank and anchor text. Fact.
I believe if you used rel="insertanythingelsehere" before a "nofollow", the link would not be followed. It had to be "follow". So Google do/did abide by the directive at link level and (a couple of months ago) when I tested again.
So I am not sure whether Google have actually closed this off now or just looking into it as Matt says ;-)

Got to ask - how did you verify that it passed PageRank? And LinkText relevancy?
(The only way I can think of is that it jsut so happened that it was the only link to a given page, from a high ranking page. No internal links to that page - just that 1 single link. That 1 single link happened to have a completely unqiue, not used on the page on in context to the rest of the site bit of text.? G have made it damned hard for us to prove anythign as Fact now adays - so I am very interested to know how you did it .... as I admit, I'll make notres and copy it :D)
I seen this idea discussed on many forums. at most sites the rel="follow" insertion would not be added at all when posting to sites with rel="nofollow" default on outbound links.
