Thanks, but I already solved it.

For the people who are interested in it:

PHP Code:

<?php
error_reporting(E_ALL & ~E_NOTICE);

require_once('./global.php');
require_once('/includes/adminfunctions_profilefield.php');
require_once('/includes/adminfunctions_user.php');

        $ids = array(1234,1235); 
foreach($ids as $id)
{
    $info = fetch_userinfo($id);
    if (!$info)
    {
        echo $id.'fail<br />';
    }
    else
    {
        $userdm =& datamanager_init('User', $vbulletin, ERRTYPE_CP);
        $userdm->set_existing($info);
        $userdm->delete();
        unset($userdm); 
        echo $id.'okay<br />';
    }
    unset($info);
}
?>

This deletes the member and all information connected to it. The posts and threads are still there, but those are simple to delete by two sql statements.
