There are three "levels" or types of
deletion:
1. Blanking --> simplest, anyone can do this and view the blanked content in
the history
2. Deletion --> admins can do this easily, other admins can see this and it
is shown in a public log
3. Oversight --> [[m:Hiding revisions]] revisions are *permanently* removed
from the database by those with the "oversight" permission, can only
be re-added by developers (I think root). However, there is a private log
that shows a *little* information. Oversights (people with the oversight
permission) are assigned by ArbCom.

Don't forget level 4: "Deleted off the hard disks completely." IIRC,
everything that was deleted (#2) before something like March 2004 was accidentally
completely deleted (#4) by the devs, and of course we only comparatively recently got true
#2 deletion for images (that is, allowing for admins to undelete).
