An anonymous employee from e-commerce giant Alibaba Group's customer-to-customer platform Taobao marketplace accused the State Administration for Industry and Commerce (SAIC) of unfair treatment over a quality random inspection report, according to Taobao's official Sina Weibo account on Tuesday.

The unidentified source, who claimed to be an employee from Taobao's fake goods crackdown unit, said SAIC has published misleading reports over a recent random inspection against fake goods on Chinese e-commerce platforms.

The report, which was posted on the website of SAIC on Tuesday, said fake goods accounted for some 63 percent of all the goods sold on the platform during the second half of 2014.

The source alleged that the method used in the inspection is flawed and did not reflect the actual level of authenticity of goods sold on Taobao marketplace.

The source further accused the SAIC of failing to uphold the inspected vendors' right to file for an appeal but announced the results of the random inspection immediately.

The source also pointed out the inspection result is vastly different from a relevant inspection result published on December 11, 2014.

About Taobao's challenge, Yang Hongfeng, an official with SAIC's e-commerce trading supervision department, said on Tuesday the purpose of the random survey is to spot fake goods and the full survey is done by a third-party service provider, whose method SIAC could not interfere with, news portal sina.com reported Tuesday.
