Interesting article. I’m using Spam Karma 2 instead but lately a few comments with just random letters in have gotten through. I think I’ll try some of your ideas. Thanks for sharing.

Hi Håvard

Yes you are right…. and thanks for letting us know :)

Though, now that I look closer at the htaccess filter, I see that I thought of this when I created it and also allowed refer fields that are empty:
RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://(www\.)?justaddwater.dk/.*$ [NC] RewriteRule jaw-comments-post.php$ - [F]

And as you can see, your comment got though correctly.

I hope you are aware that the referrer field is optional and some privacy filters blocks it, so comments sent with no referrer field should be let through. I’m posting this without one, so I guess this serves as a test as well. :)
