Top Commenters: exclude admin

回来的时候，我在这里发现了这个黑客来显示顶级评论。它工作得很好。但是我想从评论列表中排除管理员。所以请帮助修改代码以排除管理员谢谢。

代码为：

function top_comment_authors($amount = 5) { 

    global $wpdb;  
    $results = $wpdb->get_results(\' 
        SELECT 
            COUNT(comment_author_email) AS comments_count, comment_author_email, comment_author, comment_author_url 
        FROM 
            \'.$wpdb->comments.\' 
        WHERE 
            comment_author_email != "" AND comment_type = "" AND comment_approved = 1 
        GROUP BY 
            comment_author_email 
        ORDER BY 
            comments_count DESC, comment_author ASC 
        LIMIT \'.$amount  
    );  
$output = "<ul>"; 
    foreach($results as $result){ 
        $output .= "<li>".(($result->comment_author_url) ? "<a href=\'".$result->comment_author_url."\'>" : "").$result->comment_author.(($result->comment_author_url) ? "</a>" : "")." (".$result->comments_count.")</li>"; 


    } 
    $output .= "</ul>";  
    echo $output;  
}
