Single post in Help Wanted! PFQ Wiki

So, I've been looking at the "Recent Changes" section, and it appears that there are at least four spambots on the wiki. They're called ASVLavonda, ‎Marcelino88J, ‎Stacie3965, and AdrianGerman. They haven't messed with any articles, but they created tthree pages of spam so far, plus stuff on two of their pages. We should get rid of them.
