According to the Linyi Hedong official account, in accordance with the relevant deployment of the Ministry of Public Security's "Net Cleaning Operation", Linyi Public Security has continued to strengthen its crackdown on online illegal activities. At the beginning of 2023, the Yihe New District Branch of the Linyi Public Security Bureau discovered an APP suspected of gambling in its work, and the capital flow was huge. According to the investigation, the APP was developed by Zhao Mou at the instruction of the criminal suspect Shi Moumou. Shi Moumou used his own and his family's identities to open multiple fund pool accounts. Members used virtual currency to exchange chips in the APP, and conducted online gambling by guessing the rise and fall of virtual currency exchange rates in different time periods. Since 2023, the public security organs of Yihe New District have successively arrested 13 suspects involved in the case, including Shi Moumou, and seized more than 10 million yuan of funds involved in the case. In May 2024, Shi Moumou and others were sentenced to fixed-term imprisonment by the People's Court in accordance with the law.
