Hm, we seem to get a lot of vandalism. I locked the site for the moment. EmacsWikiAdministrators can lock and unlock the site via the Administration link at the bottom, then Password link to make sure you’re logged in as an administrator, and once you are, the Administration page will show a Lock site or Unlock site link.
(If you don’t know what I’m talking about, check out RecentChanges including rollbacks.)
Update: I added mail.wishmobile.ca to BannedHosts.
