Roll back edits done by a vBulletin moderator or admin done to a post? For example, take Wikipedia into account. When someone edits a page, there is an option for the administrator to reverse the edits and put the "post" back in its original form. On my site, I am seeing people editing other peoples post, and it's been reported that some moderators are helping their friends out by editing things out that are breaking the rules, making it hard for us admins to discover the truth.
If anyone can help, I would be very greatful!
