Nah, the flock will lock out based on user accounts on the server - not based on which script is what.

If you want to be anal about it, edit your global.php file with something like:

if(!defined('MY_SCRIPT_CHECKING_VARIABLE'))
{
  die('Hacking attempt!');
}

Then in EVERY SINGLE php file for vBulletin, add this before including global.php:

define('MY_SCRIPT_CHECKING_VARIABLE', true);

You would want to customize the variable MY_SCRIPT_CHECKING_VARIABLE to something very unique. That's an old tried and true method of preventing any alternative scripts from accessing anything it shouldn't.

However, it's not exactly practical because you have to edit every single php file, and you have to keep doing it for every single upgrade.
