new thread in specific forum

[Acers]

I am trying to use some content a user enters to create a new thread in a forum of my choice.
Now key thing is that the user is not registered on board.

now trying this code

PHP Code:

$newpost = array(
    'emailupdate' => 9999,
    'userid' => X,
    'username' => 'bot name',
    'title' => $subj
);
eval('$newpost[message] = "' . fetch_template('contact_temp') . '";');
require_once(DIR . '/includes/functions_newpost.php');
    $vbulletin->userinfo['userid'] = 1; 
    $vbulletin->userinfo['username'] = "bot name";
build_new_post('thread', $contact_foruminfo, array(), array(), $newpost, $errors); 


*where X is the "bot"s userid

prob being that the thread is made but it comes up as moderated. Although i can see it as admin, but i would still prefer it not being shown as moderated. Anyway to do this?
