Can’t fetch comments.
Query: SELECT `posts_table`.`post_title`, `spam_table`.`karma`, `spam_table`.`id` as `spam_id`,`spam_table`.`karma_cmts`, `comments_table`.* FROM `wp_comments` AS `comments_table`, `wp_posts` AS `posts_table` LEFT JOIN `wp_sk2_spams` AS `spam_table` ON `spam_table`.`comment_ID` = `comments_table`.`comment_ID` WHERE `comment_approved` = ‘1′ AND `posts_table`.`ID` = `comments_table`.`comment_post_ID` ORDER BY `comments_table`.`comment_date_gmt` DESC LIMIT 30
SQL error: Unknown column ‘comments_table.comment_ID’ in ‘on clause’

(the same manual command in the “mysql” shell leads to the same error)

However, “select count(comment_ID) from wp_comments as comments_table” works fine, the column is present.

Do you know if there is a problem with table renaming in ON clauses? The following seems to work fine:

select a.comment_ID from wp_comments as a left join wp_comments as b on a.comment_ID=b.comment_ID limit 1;

If you want SK2 to obey the WordPress option “An administrator must approve the comment (regardless of any matches below)” (under Options … Discussion) – Then you can use this sk2 plugin sk2-moderate-plugin which Richard mentioned above. I will be soon extending this plugin to support some more of the main WordPress comment moderation options as I have already offered to Richard.

As for the following comment:

I’m using WordPress 1.5.2. SP2 is “approving” comments that it thinks are not spam. This is not proper behavior, IMHO, for any kind of software, I don’t care how good it is. I’d rather have false positives than comments being posted that I can’t review/moderate first.

The way in which SK2 work is designed based on the fact that once you start getting a lot of comment spam coming in manual moderation becomes a chore and takes up a lot of your time – therefore if the comment passes through the SK2 checks and ends up with positive karma then it goes live straight away – this behaviour stops people double posting because there comment doesn’t appear and will in heated/busy discussions help the discussion flow much quicker – unless you sit infront of you computer 24/7 approving true comments that are sitting in moderation then you will find that enforcing the moderation as you suggest will stifle the discussion heavily.

The most important thing to remember is that if a comment slips through SK2 and ends up live that was spam enure that you mark it as spam using the SK2 admin pages – this way SK2 will learn that the IP used by the spammer and any urls in the comment / url of the spammers website are bad and add them to the blacklist so they won’t slip through again.
