Bad Behavior is behaving badly

Part of our spam blocking system here at Adventus.org has suddenly become overzealous. EVERYTHING is getting blocked, not just comments, such that I had to log into the server and rename a file before regaining access to the system.

Until I can figure out what is going on, only currently registered users of this site will be allowed to post comments. Sorry, but that is the way it has to be until this gets straightened out. But please do keep reading!

UPDATE: The author of the anti-spam system Bad Behavior has posted a patch. We are back to business as usual.
