In 2020, China's online literature pirates lost more than 6 billion yuan. Fighting against copyright was an important social problem. There were many reasons for the loss of online literature pirates, including the survival of pirated websites, the degree of rampant pirates, the strength of the law against pirates, and so on. The survival of online literature pirates was more complicated. Pirate websites often had a fixed audience and source of income that was difficult to attack. Therefore, many methods were needed to fight against pirates, including technical means, legal means, cultural supervision, and so on. Piracy was also one of the difficulties in cracking down on copyright. Piracy of online novels often had a high rate of pirated copies and spread quickly. Pirates could use various means to spread the pirated copies, making it difficult to track and crack down. Therefore, it was necessary to establish a more efficient information sharing mechanism to improve the efficiency and accuracy of cracking down on pirates. The strength of the law was also an important guarantee for cracking down on copyright infringement. However, due to the complexity of the type and scale of online literature, the legal means to crack down on copyright infringement needed to be more detailed and comprehensive. At the same time, it is necessary to strengthen the punishment of pirates and increase the legal cost of pirated goods to curb the act of pirated goods. Cracking down on copyright was a complicated social problem. It required comprehensive consideration of many factors and various means to effectively crack down on copyright and protect the legitimate rights and interests of online authors.
