It's the first time that the Internet behemoth has disclosed data related to its crackdown on counterfeits.
"From Alibaba Group's perspective, we bear a serious responsibility in this fight against counterfeits," said Alibaba Chief Executive Jonathan Lu in a statement.
A team of 2,000 staff works in the battle against fake goods, which includes hackers, authentication specialists and data modeling analysts, reported Beijing Times on Wednesday.
Alibaba plans to launch a "strike out" standard next year to tackle counterfeits, which means accounts will be frozen permanently if a brand files complaints against the same seller three times, said Shao Xiaofeng, the company's Chief Risk Officer, at a press conference on Tuesday.
Alibaba is expected to clamp down against counterfeits with greater aggression, particularly as it debuted at New York Exchange with a record-setting $25 billion listing in September.
Ma said at the World's Internet Conference in Wuzhen last month that only the Internet can solve the problem of counterfeits.
"After some research among fake goods producers in Guangdong and Fujian provinces, you may find that they are now afraid to sell their products on Taobao, as we can track them down easily and report to the police," he said.
