Comment management in WordPress isn’t too hard when you manually approve each comment. You know which comments you’ve seen, and which you haven’t. The only downside is that you have to approve the comments before they appear. Comment Inbox gives you the ease of the moderation queue with the freedom of unmoderated comments. It’s a better way to deal with spam and bacn on your blog.
Here’s how it works:
<ul>
<li>All comments except caught spam go into moderation (renamed “Comment Inbox”)</li>
<li>All comments in your Comment Inbox immediately show up on the blog — so conversations don’t wait on your moderation skills</li>
<li>There are three actions that can be performed on comments in your Comment Inbox: Archive (i.e. mark as read), Spam, Delete</li>
<li>When your Comment Inbox is empty, you can rest easy knowing you’ve dealt with all your new comments</li>
</ul>

CubePoints

It's a great plugin with some issues:
Test Environment:Wordpress 3.9.2+the twentyfourteen theme,without any other plugins.
1. I18n:
1.1 Warning: _() expects exactly 1 parameter, 2 given in xxx\wp-content\plugins\cubepoints\modules\donate\donate.php on line 165
it should be:
 'somethingWentWrongText' => __('Oops, something went wrong! Please try again later.', 'cp');
1.2 the backup.php file should add some ,'cp'to _();
1.3 line 80 of post_authors_points.php should be:
_e('Comment on your post was removed','cp'); and so on;
2. BUGS?
2.1 the ajax user search form on the wp-admin/admin.php?page=cp_admin_add_points page may be have some issue;
2.2 if I activate the Paid content module and set the 'Multiply points earned by' to 2, when some user pay for a post need to pay 10, Cubepoints will deduct 20 points from the user's account.
3.for better I18n:
/**
 * Update Cubepoints database for better i18n support
 * @author suifengtec http://suoling.net/cubepoints-mysql
 * @since 2014.09.09
 */
add_action('init','cwp_update_cubepoints_db_for_i18n');
function cwp_update_cubepoints_db_for_i18n(){
if(get_option('wp_cp_has_be_updated'))
 return;
 global $wpdb;
 $charset_collate = '';
 if ( ! emptyempty( $wpdb->charset ) ) {
 $charset_collate = "DEFAULT CHARACTER SET {$wpdb->charset}";
 }
 if ( ! emptyempty( $wpdb->collate ) ) {
 $charset_collate .= " COLLATE {$wpdb->collate}";
 }
 $charset_sql="ALTER TABLE <code>{$wpdb->prefix}cp</code> DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci";
