I was getting so much trackback SPAM that I gave up deleting them until I could figure out a better approach, which I implemented just now. When you trackback to my blogs, I do an HTTP request of the URL and double check that you are actually linking to me. Let's see if things improve.
If this actually works, then the next step is to apply that routine to all previous trackbacks and get rid of all the bad karma Google Juice in my blog comments.
Update: This worked! I encourage others to copy the algorithm.
