Introducing Hide Trackbacks – keep the benefits of track- and pingbacks (know when someone writes about posts) while keeping the comments clean and uncluttered.
After enabling the plugin, trackbacks and pingbacks are no longer shown on your posts and the comment count is updated correctly to reflect this. They remain accessible via the admin panel.

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.
