B2evolution antispam list

Before I implemented comment captchas on this blog I was flodded with comment spam. Captchas helped a lot! Like removing 95+% of all comment spam, however some still gets through. Deleting a spam comment now and then have irritated me greatly, but until earlier this week I haven't really done much about it.

After just a bit of research I decided that my first move was to automatically pull the B2evolution antispam list. I also considered Akismet but one step at a time.

Here is the simple script called from cron I use to pull the updates:

 #!/bin/sh

site=http://example.com/admin.php
name=username
pass=password
cookies=`mktemp`

wget -O /dev/null --post-data="login=$name&pwd=$pass" \
        "${site}?ctrl=antispam&action=poll"

It's not perfect since at least one comment spam went through already.

I'd like to hear what other people to prevent comment spam (other than disabling comments :-) )?
