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…
