I've been thinking this through a lot, struggling to find something of value to lock. Every time I got to the conclusion that if you make White-hat stuff, you're way better off selling it directly rather than giving it out for a CPA sale. Which begs the question on my part, is there anything White Hat that you can possibly lock to get leads? Because in most cases this is what I see being locked: Someone else's software Someone else's themes Someone else's Keygen Someone else's book Someone else's album Someone else's movie. For it to be white hat, you would have to produce something of value or simply something that is needed. And let's be honest, if you've written your own book, made your own movie, software, theme or template then you're way better off just selling it directly rather than locking it with CPA. Curiosity kills me on this one, what can you possibly lock and gain an income efficiently with CPA/PPD?
