In an emergency, and if no Commons oversighter is immediately available, please contact a steward. Stewards should also be able to help if you need assistance with a cross-wiki problem .
There are currently 5 oversighters on Commons.

What is an oversighter? 
Oversighters are administrators with the technical ability on Wikimedia Commons to hide (suppress) data so that it can no longer be seen by normal editors. They are able to suppress revisions from a page or media file history, user names in edit histories and logs, and portions of individual log entries.
Suppressed data remain permanently inaccessible through the wiki. Therefore, it cannot be accidentally restored when a page is deleted and undeleted. Suppressed data can be viewed and restored only by oversighters.
According to the global policy, suppression is approved in four cases:
- Removal of non-public personal information such as phone numbers, home addresses, workplaces or identities of pseudonymous or anonymous individuals who have not made their identity public, or of public individuals who have not made that personal information public.
- Removal of potentially libelous information either:
- a) on the advice of Wikimedia Foundation Legal Counsel or;
- b) when the case is clear and there is no editorial reason to keep the revision.
- Removal of copyright violations on the advice of Wikimedia Foundation counsel.
- Hiding of blatant attack names on automated lists and logs, where this does not disrupt edit histories. A blatant attack is one obviously intended to denigrate, threaten, libel, insult, or harass someone.
Meta policy on oversighters 
How do I become an oversighter? 
First, read Commons:Oversighters/Howto.
When you are ready, make your request using the box below, replacing Username with your own user name.
For greater visibility, all requests made here are transcluded onto the central Commons:Requests and votes page.
Please note any registered user may vote here although those who have few or no previous edits may not be fully counted. It is preferable if you give reasons both for Support votes or Oppose ones as this will help the closing bureaucrat in their decision. Greater weight is given to argument, with supporting evidence if needed, than to a simple vote.
