There are three "levels" or types of deletion:
- 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).

Actually, it would be 4) unlinking, where you delete the entry in the file system that says where the file is on the hard disk, and 5) shredding, where you overwrite the file in zeros.
