This paper investigates the "Exploitation Business" model, which capitalizes on information asymmetry to exploit vulnerable populations. It focuses on businesses targeting non-experts or fraudsters who capitalize on information asymmetry to sell their products or services to desperate individuals. This phenomenon, also described as "profit-making activities based on informational exploitation," thrives on individuals' limited access to information, lack of expertise, and Fear of Missing Out (FOMO). The recent advancement of social media and the rising trend of fandom business have accelerated the proliferation of such exploitation business models. Discussions on the empowerment and exploitation of fans in the digital media era present a restructuring of relationships between fans and media creators, highlighting the necessity of not overlooking the exploitation of fans' free labor. This paper analyzes the various facets and impacts of exploitation business models, enriched by real-world examples from sectors like cryptocurrency and GenAI, thereby discussing their social, economic, and ethical implications. Moreover, through theoretical backgrounds and research, it explores similar themes like existing exploitation theories, commercial exploitation, and financial exploitation to gain a deeper understanding of the "Exploitation Business" subject. learn more on arXiv
