Gojipedia:Oversight

Users who are given the oversight flag ('oversight' user group) have access to Special:HideRevision, through which they can permanently hide revisions of pages from all users, and Special:Oversight, where they can view a log of such actions and the content of the hidden revisions. This right is only granted to exceedingly few users who are at least 18 years of age and have identified themselves to the Wikimedia Foundation.
