But if you're going to be open about the reversion, why not just undo and leave a quick edit summery? It's a couple of extra clicks to help the users understand what went wrong. Rollback should always be a last resort, and if you are going to resort to rollback and not leave an edit summary of why the edit needs to be reverted, you should have reached a point that you don't want people to know the edits have been undone. Otherwise, undo and leave an edit summary! It's not that much more effort, and much more informative to everyone.
