What is the deal with the current comment spam

Overnight another 103 spam comments posted to the blog.

What the heck is the deal with these?

I used to think that the idea was to get the links published in lots of places so that those links came up higher in Google searches for those particular uhhh.... topics.

But I took a couple of the latest batch and tried the links - and they don't even go anywhere or resolve at all! What the hell do these folks hope to accomplish with these ads? It don't make no sense to me... color me aggravated.
