CCwiki allows other sites to publish content from stack exchange given proper attribution. However, it is unclear to me if they can publish something from stackoverflow and attribute it to stack overflow if it was deleted from stack overflow. When a post is deleted from stack overflow does the publisher of the other website have an obligation to delete the copied content if they are notified of the SE deletion? What if the SO post is libelous or otherwise offensive and the attribution makes SO look bad? What happens if the original user contacts the other website and specifically asks for it to be removed or unattributed to his account?
this is effectively the same question as How does the Creative Commons license affect deleted content?. However, that question does not address the scenerio of "what happens if the user contacts the other website asking for them to remove the content?" aspect.
