WordPress.org

Does this plugin add any database tables?

No.

Will this plugin work with Disqus/Intense Debate/js-kit?

This will only work with the default WordPress comments system.

If I disable javascript will it still work?

No. This plugin requires javascript to be enabled in the users browser for the comment to be accepted.

The checkbox doesn't appear in my comment form

The checkbox only appears for logged out users. If you're logged out, it only shows if you have javascript enabled. If you are logged out and have javascript enabled and it is still not showing then you need to have the comment form action active in your comments.php theme file

do_action('comment_form',$post->ID);

I am allowing trackbacks but I am being trackback spammed! what do I do?

You can download any of the number of trackback validation plugins which will check the trackback before allowing it or not.

After having no spam I am now getting LOTS of spam, what do I do?

Sometimes scripts can semi automate spam and they know what the checkbox name is so they can automatically tick it. Change the checkbox name value in the settings page to something new (like change the number) so the autmoated systems don't know what the checkbox is called any more
