Authorities have shut down 35 online dating websites for "seriously violating regulations and presenting false information", according to the Cyberspace Administration of China.

The violators were the second batch of websites reported by the public and jointly investigated by the administration and other related government bodies. The illegal portals also circulated pornographic content, the administration said.

The administration launched its latest crackdown on illegal online dating websites in February. It shut 65 websites on Feb 17 with the help of reports from the public.

The websites were closed for various reasons, including the circulation of pornographic content and taking part in pornographic scams.

The violators face penalties based on their illegal activities. The administration also urged online dating portals to register their businesses. Those which are suspected of breaking the law will also be tracked, it said.

Many online dating websites have built trust among the public by protecting the rights of users, the administration said. Regulating the sector is a long-term effort and needs public support, it said.
