Adult industry rules are perfect!
 

Almost everyone can earn some bucks in this industry. If a new guy comes and asks for advice how to earn some money, you just tell him to go posting galleries/freesites or to build a few TGPs. That won't make that guy rich, but the fact is that the rules of adult industry lets eveyone to come in freely and to take a piece of the pie.

Casinos have also something similar - free lotos. It's quite easy to build them but I'm not sure who is gonna to send you traffic for free.

The rest of mainstream is cruel.

Anyone knows how these rules have evolved to the current situation? I'm talking about Galleries|TGPs|Sponsors system.
