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 <code>X-Pingback</code> header WordPress sends 
2. Causes any <code>bloginfo('ping_backurl')</code> 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.
