The popular " flooding " on the Internet referred to posting a large number of repetitive, meaningless, or negative content on forums, communities, social media, and other platforms in order to attract attention, increase the number of posts, and earn points or economic benefits. This kind of behavior was known as " posting " or " brushing posts ". It was also known as " flooding magic weapons " or " brushing presence." In the online community, some websites or forums would take technical measures to limit and punish "water posts", such as limiting the number of posts, lowering the level of the account, and blocking the account. Although these measures effectively curbed the spread of some "water posts", it also caused some controversy because some users felt that these measures violated their basic rights. Therefore, some people would still use other methods to " brush posts."
