Hate Pingbacks and Trackbacks? Me too. Pingback Killer disables of of WordPress’ built in pingback functionality. This is a very simple plugin that… 1. Removes the X-Pingback header WordPress sends 2. Causes any bloginfo('ping_backurl') call to return an empty string 3. Hijacks the two options relating to pingbacks 4. Removes the /trackback/ rewrite rules There are no options pages, it just works. Bugs? Problems? Get in touch.
