PayDelete

The DeadDelete Plugin for WordPress allows developers to make removing outdated content from their sites easy by allowing users to click a button that checks source URLs for 404 or 301 status codes. If the source returns a 404 the post is trashed. The same is true in cases of 301s if the final destination is known to be a destination for missing content.
DeadDelete is designed primarily for aggregators that copy content from other websites with source attribution links included. It is ideal for RSS based auto-blogs that include a large amount of content from other sources. With DeadDelete a user can click a button when they notice that an article is based on a source that no longer exists and remove your copy so that you don’t have to.

More features will be added in the future and in the paid version.
Two custom database tables are created on activation but contain only few informations. It will be delete when removing the plugin (not on simple desactivation). All the created posts stay in the WordPress database after removing, like any custom post type.
