Commons:Revision deletion

Shortcut: COM:REVDEL

This page is considered an official policy on Wikimedia Commons.

It has wide acceptance among editors and is considered a standard that everyone must follow. Except for minor edits (such as fixing typos, or bringing information up to date), please make use of the discussion page to propose changes to this policy.

Revision deletion (also RevisionDelete or RevDel) is a part of the Commons software (MediaWiki) which allows selective hiding from public view of posts, file versions and log entries by administrators, as well as review by any administrator of the correct use of the tool. Entries still appear on the public wiki (as inaccessible items, with the original content removed), and any user may request that an administrator review a RevisionDelete action, to determine whether its removal was reasonable. Note that RevisionDelete does not delete data from the Commons servers, it merely hides it from public view. Administrators can see RevisionDeleted content, and, if necessary, reverse the deletion.

Overview

The RevisionDelete dialog. The suppression option is included for completeness, although this is only visible to users with oversight access.

To hide or unhide a revision or a log entry, admins can click a small "(del/undel)" button next to a relevant revision, diff, or log entry. There are normally three options to choose from:

• Delete revision text
• Delete edit comment
• Delete editor's username/IP

In addition, users with the suppressrevision right (namely oversighters) have an additional option, to Suppress data from administrators as well as others.

When Revision Deletion may be used

Currently there are no specific guidelines for use of the Revision Deletion tool. It is considered an additional tool for enforcing other Commons policies, and so for example may be used in all cases where regular deletions are permitted but where just a revision needs to be removed. Because of the effects on transparency, it should be used with appropriate caution.

The standard reasons presented to administrators when using the tool (from MediaWiki:Revdelete-reason-dropdown) are:

• Copyright violation
• Inappropriate personal information
• Potentially libelous content
• Purely disruptive material
• Grossly insulting, degrading, or offensive material
• PD-Art image with non-free frame
• Non-public identifying or personal information
• User edited while logged-out, revealing IP

Note that this list is in no way exhaustive; the standard reasons are merely provided for convenience, and administrators may provide any reason they wish (though it should be reasonably clear what policy or policies are being enforced). Other common uses include:

• As the result of a deletion request where only one version of a file requires deletion
• To delete a version of a file which includes an identifiable person in a private location who has not given consent to the upload (see Commons:Photographs of identifiable people)

Revision deletion is used sparingly

Please note that revision deletion is used sparingly and is not (for example) used to hide the fact that there were several unsuccessful attempts at uploading variants of an image, or that there has been some back-and-forth over which of two versions of an image to use. Discussions about revision deletion consume participant time, deleting revisions consumes administrator time, and deleting revisions does not save any disk storage space.

How to request Revision Deletion

In order to avoid the Streisand effect, there is no dedicated on-wiki forum for requesting RevDel for privacy reasons. You can send a message to any administrator either at their talk page or by email if privacy is a concern. You can also request revision deletion on IRC using #wikimedia-commons. If the revision you're reporting could be subject to oversight, follow the procedures at Commons:Oversight.

For some cases, there are specific templates to request revision deletion:

1. {{Non-free frame revdel}} – to request deletion of old revisions of a PD-Art image with non-free frame, where the non-free frame has been cropped out in recent revisions
2. {{Overwritten revdel}} – to request deletion of revisions with unknown source, authorship and/or licensing which have been uploaded in violation of Commons:Overwriting existing files

Appeal, discussion and reversal of actions

Actions performed using this tool remain visible in the public logs. They are subject to review by other administrators (who can see the revision-deleted material), either at their own discretion or on request. As with other administrative tools, good judgment and appropriate use are expected; improper use can lead to sanctions or desysopping.

Revision deletion is expected to be used sparingly, and disputed cases should not normally be reversed without either prior agreement with the deleting admin or a consensus emerging from community discussion about the case.
