Dag and http://www.krisbuytaert.be/blog/ have been talking about comments and tracebacks.
I myself use WordPress and also get a lot of SPAM in my comments, be it traceback or actual comments. But WordPress has the Askimet plugin, you can run it over your pending comments and the SPAM will be mostly filtered out. Don’t you have that feature for Drupal?? Kinda hard to believe it’s not available.
Anyone comments about using WordPress or Drupal. I want to make the switch as I’m somewhat of a patriot and want a new Blog to play with 🙂
