In a nutshell, TrackBack was designed to provide a method of notification between websites (more information).

Unfortunately, this mechanism is often a source of spam. You can disable it in two step.

(a) Disable trackbacks/pingbacks for new post/page:

Go in Setting->Discussion and uncheck “Allow link notifications from other blogs (pingbacks and trackbacks) ”

(b) Disable trackbacks/pingbacks for old post/page:

On machine where database lives (assuming mysql):

mysql
mysql> use database_name;
mysql> UPDATE wp_posts SET ping_status = 'closed';
mysql> bye

That all!
