Template:OldWarning

Usage
This Template is used to warn editors a first time for:
 * vandalizing pages and/or talk pages,
 * making disruptive edits,
 * not maintaining good faith towards other editors,

and if the edit is repeated, the user who the warning was given to may be blocked. You may cut and paste the three main reasons above or just write a new one. This warning template should only be used by administrators; other editors should simply leave a polite note on the offending editor's talk page, and if anybody but an admin uses the warning box, they'll be given a warning also, but if repeated, they'll not be blocked.

Update - In response to this discussion and this discussion, the requirement that users keep a warning on their user talk page has been removed. Users who remove warnings from their user pages should not receive a warning or block for doing so, as forcing a user to keep a warning on their page is a "badge of shame," which should be avoided.

Rather than keeping track of warnings, an administrator issuing a warning should write an appropriate edit summary which will be available in the page history. This summary should include a description of the offense(s) behind the warning, and (if possible) a link to the policy in question (wiki linking is enabled in summaries). This way, an admin can easily check the edit history of a user to see when they were warned and what they were warned for, even if the warning is no longer on the current revision of the page.

Warnings issued to unregistered contributors should be removed within a few weeks of issuance, if the contributor becomes inactive and the warning is still on their page. To use, type:  ~
