The 'Human Flesh Search Engine' is a Chinese internet term originating in the early 2000s, referring to the collaborative efforts of netizens to track down people of interest through crowdsourced research. Unlike traditional search engines powered by algorithms, this phenomenon relies on the collective intelligence and time of thousands of individuals to uncover private identities or expose wrongdoings. While it started with harmless inquiries, it evolved into a potent form of cyber-vigilantism and public shaming, often raising ethical questions about privacy and 'internet justice.' Today, it represents the terrifying and fascinating power of the internet mob to find anyone, anywhere.
