How about setting up some procedures for requesting review copies:

* As part of posting notices, Mike could require the producer of the product to indicate how many copies theyre giving away and an email address for requests
* If you request a copy, you should include the URL of an already live website about the product so that the producer knows you're serious
* The producer should post in the thread here when all copies have been sent out, and delete the email address to make further requests bounce

Sounds simple enough to ensure that these review copies do not attract freebie seekers.
