I've been experiencing an increasing amount of comment spam on FOB lately—enough that's it's getting to be a pain to moderate. I just tweaked CAPTCHAs to be a little harder (sadly) and upgraded Drupal's CAPTCHA package to the latest version, which apparently resists certain attacks. Hopefully that will fix the problem. If not, I'm going to have to figure out something else, and I'm afraid it's not going to be pretty. Sorry for the inconvenience. (B)
