I do the following to create hundreds of users at a time.

$userdm = new vB_DataManager_User($vbulletin, ERRTYPE_ARRAY);
$userdm->set('username', $tsData[uName]); // My new name is in this array.
$userdm->set('password', 'admin@yoursitename.com);
$userdm->set('email', 'adminXYZ@yoursitename.com);
$userdm->set('usertitle', 'Auto-Generated User');
$userdm->set('usergroupid', 9); // My own custom user group for auto-generated userID's
$tsData[UID] = $userdm->save();
$db->query_write("UPDATE user SET email = '' WHERE userid = '$tsData[UID]'"); // Erase the email address so you can use it over again.
