As some of you have noticed the spambots have been targeting the site again. Drupal doesn't have any built-in spam tools -- I'm using a module that is still being developed for Drupal 6, and it's missing a few features that would make administering it a lot easier. The module has promise but it's development pace is slow (it's the work of one developer in his spare time) so I'm using what I have with the hope that there will be more functionality down the road.
At the moment, the tool I'm using snags most of the spam that hits the site. However, about once a month there's a volley of spam that manages to get through the filters that I have to go take care of myself. We appear to be in one of those incursions at the moment.
