Since the wiki is very low volume, there have been
almost no
changes over
the past month, other than spam. The simplest method it would
seem then
would be to do a site roll-back for one month.
Is this possible?
Do you have backups? If so, just import an old backup. If not, maybe you
can use the Nuke extension
(
http://www.mediawiki.org/wiki/Extension:Nuke). Others may have better
options.
