Mass Rollback on MediaWiki

"You could always just restore your database from your backup, right?

The revert methods on meta.wikimedadotorg should work, but as you point out that's not going to fly on a ton of pages.

I would think you could manually go into the MySQL db and purge back to before the spambots, but I'm not sure how that would work."

"http://www.mediawikidotorg/wiki/Extension:Nuke is an extension that lets you delete all pages created by a user/IP. The JS script mentioned in a comment by Hello71 lets you rollback all changes from a certain user. Used together, it works pretty well.

For your specific case of having 12 changes to each page from multiple bots, I don't know how well that can be handled."
