Only staff and perhaps VSTF have the ability to remove revisions or entire pages from history and logs. This will generally be done if they are a violation of TOU (e.g. posting illegal materials, or exposing private information).

Such actions are hidden from everyone (including admins) except users with the right to actually remove (or view) such contents.
