The community of shared future in cyberspace is not only the common home of humanity, but also encompasses a wide range of circles, consisting of different natures, scales, and characteristics, with rich and diverse circle cultures. A good circle culture can shape people's common ideological foundation, unleash vibrant spiritual power, and promote economic and social development. Among them, fan culture plays many roles such as entertainment, comfort, communication, etc. With the intervention of commercial forces, it also plays a strong economic role, and celebrities can generate traffic and obtain economic income through it. What is the inherent law of celebrities monetizing traffic through fan circles? The reason is simple, it is the "acquaintance" effect in communication studies. Fanquan is a circle culture, also known as an acquaintance culture, which can make consumers in the circle feel defenseless and accept everything from each other like lovers. People initially accepted celebrities as a form of spiritual consumption. Due to the fact that celebrities and the cultural products they participate in creating meet the spiritual and cultural needs of consumers, they accept and identify with the celebrity's discourse system, behavioral habits, ways of thinking, and values. Many fans have actions that are highly consistent with those of celebrities. Whenever a celebrity has any words to advocate and actions to practice, consumers will inevitably be highly synchronized and responsive. Previously, fans mostly engaged in spatiotemporal interaction and communication with celebrities through mass media. After the Internet has become the basic way of life for people, stars themselves are an influential medium. The online zero time and space difference communication makes stars not only spread widely but also have high credibility under the superposition effect of mass communication and interpersonal communication, which produces incomparable communication effects with the popularity of the public. Therefore, when celebrities put down their bodies to advertise for material products, the spiritual products of Yangchun Baiyue become the material products of the lower class, meeting the material needs of consumers. Material demand is the rigid demand of consumers. When the material products recommended by celebrities are not significantly different from other products, or sometimes have higher prices than other products, as long as they are within the critical acceptance range of consumers, consumers will not hesitate to purchase the products recommended by celebrities. Consumers have a mentality of minimizing the decision-making cost of avoiding consumer product choices. If there are acquaintances who make choice decisions on their behalf, consumers will inevitably be willing to hand over the choice to trusted acquaintances, and celebrities are these "acquaintances". This is the inherent law of celebrity traffic monetization. It is precisely because of this law that some stakeholders rush in, pursuing profits without considering social responsibility and public interests, like black holes, involving one fan circle after another, becoming tools for unfair profit, generating various social problems, and eroding mainstream social values and ideological forms. We need to have a correct understanding of the positive and negative effects of fan culture, and use various strategies to control it according to the situation, making it a beneficial positive subculture.
