Why is it right to fill in ISBN code when Pinduoduo sells the same book that others can sell? I uploaded the same book and said it was banned and refused directly?

I understand that Pinduoduo is an e-commerce platform that allows sellers to sell all kinds of goods, including books. However, the e-commerce platform has its own audit mechanism and rules to ensure the legitimacy of goods and conform to the policies of the platform.

I can give some possible explanations about your question, but you may need to consult an authoritative person in Pinduoduo to get an accurate answer. Here are some possible reasons:

1. Different platform policies: Different e-commerce platforms may have different auditing standards and policies for certain commodities. Pinduoduo may have imposed restrictions or bans on certain books or books with ISB numbers.

2. Content review: Pinduoduo may review the uploaded books to ensure that they do not violate relevant laws and regulations, contain infringing content or violate platform regulations.

3. Quality of platform maintenance: Pinduoduo may have formulated some standards that require sellers to provide genuine, legal and high-quality goods. If your book doesn't meet these standards, it may be rejected.

In short, the platform supervision and audit mechanism is to maintain market order and user interests. If you have any questions about the audit results of Pinduoduo, I suggest you directly contact the customer service or the official in Pinduoduo for detailed explanation and help.
