Robots.txt hakkında bir soru

Merhaba, vbulletin 4 + vbseo kullanmaktayım. robots.txt dosyam aşağıdaki gibi.

Disallow: /forum/paneladmin/
Disallow: /forum/clientscript/
Disallow: /forum/cpstyles/
Disallow: /forum/customavatars/
Disallow: /forum/customprofilepics/
Disallow: /forum/images/
Disallow: /forum/panelmod/
Disallow: /forum/ajax.php
Disallow: /forum/attachment.php
Disallow: /forum/calendar.php
Disallow: /forum/cron.php
Disallow: /forum/editpost.php
Disallow: /forum/global.php
Disallow: /forum/image.php
Disallow: /forum/inlinemod.php

Disallow: /forum/showgroups.php
Disallow: /forum/subscription.php
Disallow: /forum/threadrate.php
Disallow: /forum/usercp.php
Disallow: /forum/usernote.php 

site /forum dizininde kurulu ve robots.txt ana ana dizinde duruyor. bunda bir yanlış var mıdır?
