The campaign to create a clean and healthy cultural environment made notable progress last year. More than 4.5 million erotic posts were deleted from the Internet by request from the office during the year, while online service providers removed about 20 million similar posts themselves. Authorities cracked a serious case of spreading erotic videos through WeChat, which involved more than 100,000 people in more than 20 provincial-level regions, including underage people. The government also exposed new means of spreading pornographic content in 2017. The public took an active part in the campaign, providing more than 120,000 leads to the office, according to the report.
