The last couple of days I've been having a new type of comment spam- the comments are all obviously real people, and are good comments for the posts they are commenting on, but they all give a link (in the website url field) to brnad new empty blogs. A whois for every url gives the same domain [privacy contact, and the blogs are all identical.
Is anyone else seeing anything like this?
One of the links, which is pretty much identical to all of them is imperialrage.com/  (I left of the http and www  so it didn't make a link).

Right now I'm simply editing out the urls and approving the comments.

On edit- going to http://www.my-ip-neighbors.com/ and putting in imperialrage.com gives a listing of all of the links in the comment spam, and shows that they are all blank and identical.
