Have no clue, but since several days ago, my blog had kept having comment spams, although CaptCha! is enabled. I have no choice but to try to activate Akismet instead.
As this is a 2.1-alpha (svn) of wordpress, it refused to store the WordPress.com API key. However, after a svn up of wordpress, it got fixed.
I deactivated plugin CaptCha! and went and saw how well Akismet could do its job. So far, Akismet caught 8 spams perfectly without missing a single one. I guess I will stick with Akismet then.
I just did not come up how can the spammer bot work around the Captcha challenge…

Hi! I’m the author of Captcha!. First of all, thanks for using the plugin.
Old versions (prior to 2.0) can be defeated (specially if you use the default md5 key in the options menu!). From v2.0 and above, it is much stronger (specially v2.5. You should upgrade, because versions older than 2.5 filters pingbacks.
On the other hand, as I explain in my blog, I’ve temporally stop using Captcha!, because I’ve found a (temporally) better solution. I explained it here. This solution will be defeated (yes
, it will) in the future, but meanwhile, I think it’s better to use it.

thanks for the info. In fact, I did try version 2.4 before this switching. As you stated in your blog, workaround this plugin is not so difficult and seems to me several bots are already adopted to it
Your better solution is the same as mine
