I found this on User:The Halo's page:
http://en.wikipedia.org/w/index.php?title=User_talk%3AThe_Halo&diff=422…
User:StrangerInParadise is explicitly using the categories in the userboxes
to stack votes against *taking categories out of userboxes to avoid
vote-stacking.* More than anything this frustrates the crap out of me
because, until now, I've only heard of a couple vote-stacking incidents. Is
there a userbox for "This user is unaware of absurd ironies"?
