Material was copied from a source which does not have a license compatible with Wikipedia;
There is no non-infringing content in the page history worth saving.
The text on Wikipedia really is an infringement of another source (Wikipedia has numerous mirrors — Make sure we're copying someone else, not the other way around)
Uploader does not assert permission, or the assertion is questionable
After notifying the uploading editor, add one of these to the page:
Remove the infringing text or revert the page to a non-copyrighted version if you can
The infringing text will remain in the page history for archival reasons unless the copyright holder asks the Wikimedia Foundation to remove it. Please note the reason for removal in edit summary and at the article's talk page (you may wish to use {{cclean}}). When possible, please identify and alert the contributor of the material to the problem. The template {{Uw-copyright}} may be used for this purpose.
However, if all revisions have copyright problems, the removal of the copyright problem is contested, or reversion/removal is otherwise complex:
* {{subst:article-cv | PageName}} from [insert URL or identify non-web source here] ~~~~
to the bottom of the list. Put the page's name in place of "PageName". If you do not have a URL, enter a description of the source. (This text can be copied from the top of the template after substituting it and the page name and url will be filled for you)
Advise the contributor of the material at their talk page. The template on the now blanked page supplies a notice you may use for that purpose.
