A total of 40 Chinese websites were closed amid China's campaign to clean up illegal online practices such as blackmail and deleting posts for profit, according to China's Internet watchdog on Tuesday.
Most of the violators were reported by the public, said a statement by the Cyberspace Administration of China.
It was the third time the watchdog had released a list of violators since the crackdown against websites which had violated the law or related regulations began in January.
The third list includes websites claiming to provide news or information, or websites that claim to belong to public relations or Internet companies.
The watchdog said it has strengthened its crackdown, as the number of violators caught has increased.
