I got hit with a similar flood of trackback spams earlier today. Unfortunately one of the reasons that I am still sticking with stupid old MovableType (spam control tools) didn’t come through as well with the pings as it has with past waves of comment spam. (Basically because there is no concept of “moderating” TrackBack pings in MovableType, so one of the layers of interdiction between your front page and the spammer is removed. The only filters that go through are the ones that are set up to block—e.g., known spammer URIs that have already been posted somewhere.)
Do you know what’s available for Drupal in the way of spam-quashing utilities? If this hasn’t been a matter of module development I should hope that people will get working on it soon…
