However, it seems pretty simple for someone to simulate a purchase. All the information (hidden fields) is in the initial FORM... So someone knowing the POST details of a Direct Return call could simulate such a POST operation, and trigger a purchase operation. Is there a way to prevent that? Thank you.

Now we have to manually keep track of all the cancelled subscriptions and deactivated related memberships.
