Comment spam pointing to other wordpress blogs?

I got about 50 “comments” overnight all with more than 4 links (thus sent to moderation queue) and they all had different email addresses and names, but similar links to other wordpress blogs, none of which had any relevance to our blogs.

I’ve seen posts on the receiving blogs saying “comment spam pointed me here.”

The content of the messages looked something like this:
Author : dylan chapman (IP: <removed IP>)
E-mail : <removed email>
URL : <removed link>

Comment:
very interesting! i liked it! extensive methods for this: <removed url>

Contact me directly for the linked too blogs.

Anybody else have this problem?
