MediaWiki:Revdelete-suppress

Suppress all revisions and logs from administrators as well as others.

Note: This will suppresses all revisions and their associated logs, and with all log items set to the highest restriction. Please be certain that every revision must be suppressed from the deleted history and user contributions, and that the edit summaries are all unacceptable. You should also check the edit summary in the page creation log. If there are items that should remain public or simply redacted, you must adjust those visibility settings to reflect the appropriate restriction level.
