At the end of the day, 'nofollow' on wikipedia has little effect, since as Betacommand points out on Wikiproject:Spam:

"Once our mirrors and scrapers get a hold of it, most drop the nofollow thus the spammers do get rewards for their actions on wikipedia."
Why would that result in little effect? It has been a while since I've played around with the math, but since Wikipedia has much higher PageRank than the mirrors, it would seem like our nofollow would still make a big difference in PageRank bump for the spammer sites.
