It seems I have found where all of the trackbacks are coming from. I was correct in assuming they were related to all of the spam related referrals I've been getting.

I wouldn't call it comment spam though, because the only thing it seems to effect is the number next to “Trackbacks” in my blog header. I don't get emails, it appears no one else can see the contents, so in the end, it seems pretty useless. The only place I see them is when logged in to the admin screens, under the “Feedback” tab.

I wonder how my RSS feed looks though....
