This plugin is a filter for the FeedWordPress plugin. If you do not use FeedWordPress this plugin will not be useful to you. The filter works by hooking the “syndicated_post” action of FeedWordPress.
For each potential post, the filter compares the post title, and either the post guide or the year-month-day of the post_date_gmt attributes.
If it finds a match of both the title and either the guide or date, it tells FeedWordPress to skip that potential post. Otherwise, it tells FeedWordPress to continue processing it however you have syndication set up on your blog.
Requires WordPress Version: 2.8 or higher
