Recently, the public security organs in Zhejiang have dismantled an MCN organization known as the "Internet Water Army" gang. According to the investigation, the gang used AI software to splice misleading materials from the network, edit them into "original" videos, and publish them on multiple platforms to seek illegal traffic rebates. Cases of using AI tools to spread rumors are not uncommon. With the rapid development of artificial intelligence technology, the proportion of AI generated content is gradually increasing, but it is also filled with some false information, some of which can be easily confused with the real, and are extremely confusing. The use of AI to spread rumors has the characteristics of low threshold, batch production, and difficult recognition. Searching the Internet, we can see websites and small programs such as "pseudo original tool" and "AI manuscript washing", which can not only create copy and help write manuscripts, but also generate pictures and composite videos. According to media reports, the organization that once published false news about the "Xi'an explosion" can generate 4000 to 7000 fake news articles per day at its peak, which is shocking. If AI is used by malicious individuals to spread rumors and false information, it may quickly spread, mislead the public, influence public opinion, and even disrupt social order in a short period of time. We must take strong measures to crack down on the illegal behavior of AI spreading rumors, and we must "crack down" and "strictly guard" against it. (New Society)
