“Caoliu” was once a popular Chinese adult website that gained significant attention both domestically and internationally. Launched in 2006, it offered various types of adult content, including images, videos, and forums. However, due to its illegal nature and violation of China's internet regulations, the site was shut down by authorities in 2011. The closure sparked widespread discussion about online censorship, privacy, and freedom of expression. Despite being offline, remnants of its existence remain on certain platforms, though accessing them is risky and often blocked. The term "Caoliu" has since become synonymous with discussions around illicit online activities and government oversight. It serves as an example of how regulatory bodies enforce laws to maintain societal norms while highlighting challenges in managing digital spaces globally.
