PIngbacks and Trackbacks...

Is there a way for me to allow the pingbacks etc, but not have the links to sites which are pulling my content via RSS? I don't want a list of links at the bottom of my site for all the other sites that are linking to my post... Especially not when they are pulling the excerpt, these sites would have little value to my members and the outbound links will take away from my site, SEO/SEM wise...

I assume if I turn off pingbacks and trackbacks, or if I unapprove the comments they will go away... but I just haven't fully grasped the whole concept here, so I figured I would post if for discussion, I'm sure others have run into this and more will in the future.
