Thread:Project:Support desk/Undo or delete everything since a certain date

I recently updated an abandoned wiki from 1.16 to 1.23.3. It had been abandoned about four years. During this time, spammers had created thousands of user accounts, created pages and made edits. I currently have the wiki locked down, so no one can make edits. I would simply like to "undo" all of the changes since (for example) Jan. 1, 2010. Only spammers have made changes since that date. I do not care if these page and user deletions are recorded in recent changes or if revision histories are kept. I have found extensions to block or ban users and IP addresses (but not to automatically delete these same users' page edits). I have found extensions to delete changes made by a particular user or IP address. But are all too time consuming and limited, given the amount of spamming. I would simply like to "revert" the wiki to its 2010 state.
