Well, while that might stop the spamming, it would kind of destroy the community-created nature of the wiki. : /
Also, you know, it'd be putting a lot of work on the few admins over there.
Anyway, if you want to chip in for now, feel free to replace the content of the spam pages with [[category:spammer]], and slap that on the talk page of the user who created it. That way, instead of having to go through the recent changes page, we can just work from the category page.
