Identical unsubscribe hashes are created for subscribers who have a contact record in CiviCRM but don;t have a drupal user account.

The result is that the first record in phplist_user_user is unsubscribed no matter which recipient actually attmpts to unsubscribe.

Would salting the hash with a timestamp work, or is it important that the hash generator produces persistent values for each user?
