Office actions are official changes made to content done under the authority of the Wikimedia Foundation. Sometimes the Wikimedia Foundation may have to delete, protect or blank a page or file without going through the normal site/community process(es) to do so. These edits are temporary measures to prevent legal trouble or personal harm and should not be undone by any user. Users may also be globally locked and prevented from participating in Commons by office actions under extraordinary circumstances. Potentially incorrect Office actions should be discussed with the Office, but the Office may not, and often will not, explain the reasons for its actions due to privacy or legal considerations.
