[geeks] Wordpress and Captcha

[Ido Dubrawsky]

I've got WordPress 1.5.2 installed on my webserver and I'm using the capcha
plugin (version 1.8) to keep blog comment spam bots from putting comment spam
into my blog.  It looks like it's working fine but I'm still seeing comment spam
come through.  Anyone have any ideas?  My logs show the following for each of
the IP addresses that have gotten their comment spam through:

211.44.0.14 - - [03/Nov/2005:11:59:47 -0500] "POST /wordpress/wp-trackback.php HTTP/1.0" 200 78
216.107.198.67 - - [03/Nov/2005:12:29:27 -0500] "POST /wordpress/wp-trackback.php HTTP/1.1" 200 78
69.211.129.65 - - [03/Nov/2005:12:38:41 -0500] "POST /wordpress/wp-trackback.php HTTP/1.1" 200 78

213.30.153.48 - - [03/Nov/2005:13:15:10 -0500] "POST /wordpress/wp-trackback.php HTTP/1.1" 200 149 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"
203.202.204.215 - - [03/Nov/2005:13:14:51 -0500] "POST /wordpress/wp-trackback.php HTTP/1.0" 200 78 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)"

Could this be a bug in WordPress?  I haven't seen anything on their site yet.
I wanted to know if others have seen this before I go to either WordPress or
to the guy who wrote the capcha plugin and ask (could it be a configuration 
issue on my site?).
