The online adult entertainment industry, as Darling (2014) showed, is a new case of low intellectual property regime, i.e. largely inefficient in preventing the massive copying of content. In this paper, we focus on alternative pornography and explore the mechanisms which contribute to the creation of pornographic content. We argue that user communities help content providers to absorb sunk costs associated with content production and distribution. Our main conclusion is that, although user communities cannot solve alone the incentive failure in online pornography, they complement and reinforce strategies which enable content producers to earn revenues from vulnerable copyrighted works.
