China Internet Network Information Center has exposed five domain name service providers that have received the most complaints from consumers but have not taken effective measures to rectify their problems.

The five parties are Xiamen Zhongshitong Network Service Co., Ltd.; Xiamen Liwang Network Technology Co., Ltd.; Xiamen YIxiang Technology Co., Ltd.; Xiamen Yucheng Technology Co., Ltd.; and Beijing Shiji Jialan Trade Development Co., Ltd.

CNNIC says these companies have not improved much after receiving CNNIC's first notice to regulate their service and are still sending intimidating emails or cheating some users. CNNIC has now handed over the complaint materials against these five companies to the local regulatory agencies to figure out how to formulate punishments.
