From my experience it's trackback spam, or using the trackback api. I
think this is a huge problem for blogs.
Our service gets hundreds of thousands of spam messages. Blocking by

keywords gets you only so far. What is really needed is some statistical
filtering system like CRM114 (or dspam but that is for mail) Problem is
these systems are not easy to deploy and maintain.
You're right, Daniel, it's all trackback spam. In the
Preferences>Settings page, I've added a bunch of words to the Spam
Prevention section, but I'm still getting it.
Trackback spam has long been the bane of blogging spam and AFAIK there
is no truly set way of dealing with it. Unlike normal comments there is
no way to add a captcha or other manual checking mechanism because
trackbacks are meant to be standardized and automated across all blog
systems.
The best thing you can do is try to use the blacklist words right now.
As Dave said, 4.0 has a new framework for using pluggable comment
validators which work against trackbacks as well, and with those you
will have more options.
