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 IP and 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.

How is it, with the "simple math question" in place, that spammers are still able to enter comments on my site and show up in the referers list? Do the spammers have program which can parse the web page and then answer those questions? If so, can we swap the math for something else like an image with numbers & letters in it?
