Here's how to revert vandalism for those who wonder:
To find spammed pages don't forget about the wiki's search function. In the most recent case a search for "blogspot.com" gives a complete list of unreverted pages. I right-click the pages up in a new window and follow the above procedure. Then closing that window brings me back to the search results.
If you find that the page is created by the spammer (there's no OK revision) edit the page and just enter "DELETION CANDIDATE" in it and also say in the summary something similar.

Is it me or are the few recent 'successfull' attacks (not from our point of view, I know) on pages that are attacked before. -- GrubbmGait
I have noticed the same, I figured it's because they have started to check the Changes page as a source for finding pages to spam. Not sure if that was intentional or just a side effect of how their SpamBots? work... My last exams are tomorrow, and hopefully after that I will be able to come up with some decent filter stuff for PEZ. -- Voidious
I think it's just an effect of that it is pages with URLs on them are more "spammable". -- PEZ
I just experienced a problem the participants page, I couldn't had a new robot (with an url), so I just replaced one of mine. -- Florent
Crap. It's my crude spam filter... I'll losen it up some. Stay tuned. -- PEZ
OK. Can you try again? -- PEZ
It's working fine, thanks. -- Florent
The last two attacks seem to avoid the blockade, cause they add several outerworld links. The links are just not visible (pixelheight = 1). -- GrubbmGait
I've seen that on halowiki.net too. There I'm using a spamblocker where I can add rules against certain patterns. Anyway they don't really avoid the block I'm trying here, only our ocular investigation. With my current block implementation some pages will always be vulnerable I think. But I've tweaked it again to minimize the number of vulnerable pages. -- PEZ
