I just whipped this up:

I’ve been struck by comment spam in the last few days with several spam comments awaiting moderation before I turned on akismet to block them.

This morning however, after 54 blocked comments, one got through akismet and I decided to try my hand at a WP plugin.

It turned out to be surprisingly easy, perhaps only 20 minutes work, including the learning of how wp plugins work for comments.

Credits to jroller for the inspiration. I guess we’ll find out if a spammer is interested in beating it - I’ve several ideas for improvements, but I’d rather keep them in reserve for when it gets beaten (which could be an hour from now, or a year :) )

    And this is a test comment to make sure I didn’t muck up the latest release :)

    Hi Steven,

    FYI, the plugin works great with WP 2.1. Also, I added another global option to query even logged in users. (I’ve had trouble with people registering junk users and then spamming.) Here are the relevant details:

        var $_query_logged_in_user_too = true; // If you want to force logged in

    users to answer the math question as well

        // If the user is logged in, dont prompt for code
    if (!$_query_logged_in_user_too && isset($user_ID)) {

    // If the user is not logged in check the security code
    if ($_query_logged_in_user_too || !$user_ID  && ($comment_type === ''))

    {

    Email me at david@coppit.org and I’ll email you the .php file if that’s easier.

    Regards,
    David

    Oops.

    $queryloggedinuser_too

    should have been

    $this->queryloggedinuser_too

    everywhere.
