I am testing my trackback function now. As you can see after setting a trackback to my posting, I will get an email to approve of delete the trackback with the IP and source url. I think this is a good way to fight trackback spam. The same goes for commenting. I can approve it or delete it just with one click. Both the trackback and comments are added to the same list as the approved ones, but with a sign in front of it and marked bold. In this way I can see which one are to be approved or deleted.
