# A hack for all pingbacks

 * As I understand it, WP by default only allows the first pingback from a given
   site or page and ignores the rest. I presume this is to reduce spam. However,
   I want to have extensive internal links on my site so people can easily get to
   related content and thought I could use the pingback for this purpose because
   it was automatic. However, there are often more than one link on a page, so the
   default set up will not work for me.
 * My search shows that this is controlled by wp-trackback.php. Near the bottom 
   of this file is the following piece of code:
 *     ```
       $dupe = $wpdb->get_results("SELECT * FROM $wpdb->comments WHERE comment_post_ID = '$comment_post_ID' AND comment_author_url =
       '$comment_author_url'");
       	if ( $dupe )
       		trackback_response(1, 'We already have a ping from that URI for this post.');
       ```
   
 * So, can I delete or comment out this portion and solve my problem?
 * If so, am I setting myself up for spam problems?
 * Is there another workaround, like setting comment author url to accept from my
   site but not from others?
 * I found a plugin called moderate pingback but it hasn’t been updated since 2008.
   I wrote to the author but have not heard back. I went ahead and installed it 
   but it did not work retroactively to add the missing pingbacks and does not alter
   the status quo for new posts, so it does not work now even if it did work in 
   2008.
