In recent years, various dating apps have emerged one after another. They claim to be friends in the same city and have blind dates with real people. They rely on high-traffic platforms such as short videos to push advertisements and pay chats to feed a group of people who try to "cut leeks". Jin Yongai, an associate professor at the Population and Development Research Center of Renmin University of China, believes that middle-aged and elderly people have a weak ability to distinguish the authenticity of Internet information as a whole and are more likely to be victims of gray property behind them.

"Video 5 yuan 1 min, voice 3 yuan 1 min, SMS 0.2 yuan." Li Jianmin recalled that he saw the dating advertisement on the short video platform and downloaded the software in a muddle. After the registration, people kept saying hello, and his words were ambiguous. He replied several times, and the page showed that he needed to buy virtual currency.
