I can't agree here.

1) Mirrors running MediaWiki on a database dump already get rel="nofollow" by
default unless they explicitly switched it off.

2) Screen-scrapers would be getting rel="nofollow" in their copies too --
something they currently DO NOT GET, thus multiplying the effect of linkspam.

While it's hypothetically possible for them to strip it, why would they bother?
It makes no difference to them, they just want text content to bring search
engine users to *their* ads and links.
