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.
