Trey Smith is from the "Internet marketing" world and a friend of Frank Kern's. Now, I like these guys (as far as I can learn stuff from them for free - spending $10K for a "mastermind"..? nah ;-)) but they seem to take approaches that.. rub some people up the wrong way (and that's putting it lightly). Nonetheless, I've still found there's a lot to learn from their experiences even if the delivery is a bit.. slick.
While a bit slick/sleazy in their approach their work revolves around using social psychology principles (social proof, scarcity etc), conversion tricks, clever copy, giving away freebies in order to build up their email lists. These guys eventually upsell on their premium products for a ridiculous price whilst offering their digital product for a "limited time only" to convert users who've got a good amount of value from their give-away products.
There's hardly any regulation in this industry and the FTC has come down hard on these guys on more than one occasion.
