SDG Wiki:Suppress

Suppression (sometimes referred to as oversight) is a form of enhanced deletion that, unlike normal page deletion or revision deletion, expunges information from any form of usual access, even by administrators. It is used within strict limits to protect privacy, remove defamatory material, and sometimes to remove serious copyright violations, from any edit, revision, page, or log entry (including, if required, the list of users) on the SDG Wiki.
