Assuming he is an honest actor in this process he can't share your submission with anyone as then they wouldn't be private. It is specified that it is he, Jordan, who will email you, he will say how he feels.

It could have been set up differently to allow for scaling but part of the drawn I think is that it's a real, named and identifiable, individual that you are contacting.

Of course "Jordan" could be a made up person and this could be a way to gather information for social manipulation or straight-out blackmail, but you know ...

I've long thought about the differences in scalability and margins when comparing service-based businesses to product-based ones.

In the ad agency world, it is all service-based for the most part still, margins are razor thin, pay is low, and the stress is massive. The problem then becomes maintaining quality of service as you scale, and efficiency of operations to keep your margins as healthy as possible. Stressed out service employees are basically the equivalent of delivering a shitty product. If it becomes a big enough loss in quality, you lose customers.
