I think it is highly likely that he is correct about this. Professional
spammers will likely monitor the effect of their campaigns closely, so
would know about this first. I would expect less wiki spam if
rel=nofollow was actually honored. Especially hidden (unclickable) links
don't have much value apart from page rank.

That certainly sounds logical for wikipedia and friends. However it sounds
kind of odd for mediawiki in general. There exists many unmaintained mw
installs just collecting spam.
It would also be interesting to know if other search engines do something
similar.
