I'm inclined to agree. It looks legit from a markup perspective (ie it shouldn't cause HTML validators to bitch at us; rel _is_ a defined attribute for <a>, and the set of values is open-ended.)
Of course it won't prevent wikispam, but with luck it will discourage it by reducing its value.
Would this tag apply to all external links, even to the "yes, this is a good link"-links? In the long run, we wouldn't hurt not just spammers but even the good guys by not linking to them in a way search engines would consider this link to be relevant.
Or is this just PageRankParanoia?
