Thread:Extension talk:BlockAndNuke/Going back further than recent changes?

Maybe there is a simple option for this that I am not seeing, but I have spam on my wiki going back further than what is found in the recentchanges table. Is there a way I can have it delete all pages no matter when they were created except by users in the whitelist? I've tried poking around BanPests.php and I can see where it is getting the info from the recentchanges table, but I'm not sure what changes would be required to have it get the info it needs from elsewhere in the db. If anyone would be able to help me I would really appreciate it, TIA.
