很多WordPress站长都常常遭到渣滓评论的滋扰，针对这种状况，采纳上面的代码可能会对你有所协助。
将以下代码退出到functions.php页面中。
应用时任何蕴含在$bad_comment_content数组内的字符，都将会被主动回绝留言。

function in_comment_post_like($string, $array) {    
    foreach($array as $ref) { if(strstr($string, $ref)) { return true; } }    
    return false;   
}   
function drop_bad_comments() {   
    if (!empty($_POST['comment'])) {   
        $post_comment_content = $_POST['comment'];   
        $lower_case_comment = strtolower($_POST['comment']);   
        $bad_comment_content = array(   
            'viagra',    
            'hydrocodone',   
            'hair loss',   
            'xanax',   
            'tramadol',   
            'russian girls',   
            'russian brides',   
            'lorazepam',   
            'adderall',   
            'dexadrine',   
            'no prescription',   
            'oxycontin',   
            'without a prescription',   
            'sex pics',   
            'family incest',   
            'online casinos',   
            'online dating',   
            'cialis',   
            'best forex',   
            'amoxicillin'   
        );   
        if (in_comment_post_like($lower_case_comment, $bad_comment_content)) {   
            $comment_box_text = wordwrap(trim($post_comment_content), 80, "\n  ", true);   
            $txtdrop = fopen('/var/log/httpd/wp_post-logger/nullamatix.com-text-area_dropped.txt', 'a');   
            fwrite($txtdrop, "  --------------\n  [COMMENT] = " . $post_comment_content . "\n  --------------\n");   
            fwrite($txtdrop, "  [SOURCE_IP] = " . $_SERVER['REMOTE_ADDR'] . " @ " . date("F j, Y, g:i a") . "\n");   
            fwrite($txtdrop, "  [USERAGENT] = " . $_SERVER['HTTP_USER_AGENT'] . "\n");   
            fwrite($txtdrop, "  [REFERER  ] = " . $_SERVER['HTTP_REFERER'] . "\n");   
            fwrite($txtdrop, "  [FILE_NAME] = " . $_SERVER['SCRIPT_NAME'] . " - [REQ_URI] = " . $_SERVER['REQUEST_URI'] . "\n");   
            fwrite($txtdrop, '--------------**********------------------'."\n");   
            header("HTTP/1.1 406 Not Acceptable");   
            header("Status: 406 Not Acceptable");   
            header("Connection: Close");   
            wp_die( __('bang bang.') );   
        }   
    }   
}   
add_action('init', 'drop_bad_comments');
