Can an AMI trial license be abused by regularly regenerating a new instance

From a publisher side, let's say I have an AMI published on the marketplace with an evaluation period limited in time not in functionalities. The AMI has a configuration export feature allowing to build the exact same box on other instances.

Can a customer, just before the trial period expires, export the configuration, import it into a new instance and terminate the old one, and do this endlessly to avoid the subscription fees?

From a reseller side, can one who resells the AMI subscriptions to 'ephemeral' customers, execute a new instance per customer. If the customer leaves before the trial ends, the instance is just terminated, if he stays the instance get switched to the paid subscription. If the majority of the customers leave before they reach the trial end, then the publisher doesn't make any profit, the reseller does.

Any thoughts on this? What the legal terms say?
