Publisher review:If an admin deletes a post or page, the plugin remembers the link for the page and issues a 410 response when that URL is requested.
The list can be manually managed.
The HTTP Specification defines the 410 response header for use when a resource has been permanently removed.
It informs robots visiting a site that the requested content has gone, and that they should stop trying to access it.
Installation:
Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.
