Exposure costs 3000 yuan per week, 5000 yuan per half month, and 8000 yuan per month. "" 760 yuan can drive a cyber riot "... Recently, a press conference by the Ministry of Public Security introduced that some" cyber water army "groups fabricated and spread false information in hot public opinion events," rubbing against hot topics "to harvest traffic, and even" creating hot topics "to coerce public opinion and mislead the public. In the special action to crack down on online rumors, more than 130 "online water army" cases were investigated and handled according to law, and more than 620 suspect were arrested. In March this year, China Internet Network Information Center released the 51st Statistical Report on the Development of Internet in China. Data shows that the number of internet users in China has reached 1.067 billion, of which 1.065 billion are mobile internet users, and 99.8% of internet users use mobile phones to access the internet. In the reality of "everyone holding a microphone", information dissemination is becoming simpler and faster, and it is also becoming increasingly difficult to distinguish authenticity. One of the important reasons is that some "online water armies" are stirring up trouble, using rumor making as their ability and traffic harvesting as their pleasure, spreading false and harmful information that misleads people everywhere. From the press conference of the Ministry of Public Security, it can be seen that some "online water armies" are showing a trend of scale and collectivization. The Shandong public security organs have investigated a case of "online water army" that involved a fan base of over 1.5 million and used hot topics to extort. Currently, three people have been criminally punished in accordance with the law; Zhejiang public security organs have investigated a case of "online water army" using group control software to provide false "comments and likes" services. Currently, 9 people have been criminally punished in accordance with the law; The public security organ in Hebei cracked a case of "Internet Water Army" that "used hot topics to hype and implement extortion", and arrested 81 suspect. The typical cases exposed this time actually correspond to two types of "online water army": either they forcefully grab hot topics and extort money, or they spread false information to seize unjust gains. In the era of the internet, the "cyber navy" can be considered both a public enemy and a public hazard. However, despite repeated severe attacks, the "cyber water army" has never disappeared. The reason for this is that the change in public sentiment is not only the "explosive point" pursued by the "online water army", but also the "selling point" for them to earn profits. In the vibrant online society, the "online water army" is like a shocking "psoriasis", which not only hinders visibility but also seriously endangers the physical health of the online society. In the vast amount of online information, there are two main forms of expression of "online water army": popular emergencies or false professional knowledge. The former focuses on time difference - often lies have already spread throughout the online world before the truth has put on its shoes; The latter focuses on knowledge barriers - faced with the marketing accounts of group operations, ordinary consumers have almost no defensive ability, and are easily biased and fall into the trap of "fake grass". The internet is not a place outside of law, and public emotions are neither tools for kidnapping public opinion, nor "leeks" harvested arbitrarily. Article 7 of the 2013 "Two High" Judicial Interpretation clearly stipulates that the provision of information deletion services through information networks is paid, or that knowingly false information is provided through information networks for payment
