Okay, that clarifies the “what” — but what about the “why”? The spammer’s info doesn’t appear anywhere on my site, no matter how many “trackback” notifications I get, so how is it helping them? What is their purpose?
I only ask because I was inclined to just leave it be since to my untrained eye it seemed completely unsuccessful, but the fact that it continues leads me to believe they must be getting SOME benefit out of it, and if that’s the case, I want to know how to stop them.
