This method is used by movie industry, if they release DVDs for reviewers. In fact, with so much piracy and sharing, I do not understand why a software doing this automatically for photo sets and/or movies has not been developed yet(?) for the adult industry. For some pirates, it's almost an obsession to release and "compete" (because it gives them "status" ), and for others it's for personal gain, maybe economic, on some level or another. Just scaring away the sources, could be enough protection to limit your loss.

This is just a suggestion, but I think any software programmers could also see some potential in this. Isn't there obvious demand and market for protection? Even affiliaties should be flagged this way, if they are given free access
