I updated my installation of antispambee to 2.4 a few days ago, and since this moment a lot of trackback spam hits my blog. I tried the updated some time ago (when it was released), but it has the same problem. I reverted then to 2.3, but was annoyed by the update notice.
Due to this experience I'm quite sure it a problem with AntiSpam Bee and not the spammers who got smarter ;)
The Spam Statistics in the Dashboard show a significant drop of recognized spam since the update, from about 15 a day to 3-4 a day.
Is this a known problem?
I didn't changed any of the options after the update.
(I have no problem communicating in German, if someone prefers...)
