This seems easy to address: when the game is first started with a review key, show a pop-up informing the player that this is a review key with certain limits.

This way, the player immediately knows he has bought an improper key, and can address this with the store it was bought. A journalist would not mind such a pop-up.

If the game stops working without warning after a few months, angry reactions are to be expected.
