As a second-hand trading platform, idle fish usually encourages buyers and sellers to negotiate their own refunds. However, in the face of illegal printing of books, the idle fish will take certain measures to protect the rights and interests of buyers.

First of all, if it is found that the book purchased by the buyer is pirated or pirated, the buyer can report the violation of the product to the idle fish platform. Idle fish will check the reported goods. If it is confirmed to be pirated or pirated books, the platform will take corresponding measures, such as downloading goods and punishing sellers.

Secondly, buyers should pay attention to the seller's reputation and product description when buying goods. If the buyer finds that the book received does not match the seller's description, he can communicate with the seller and ask for a refund. If the seller refuses to refund, the buyer can apply for the intervention of idle fish. Idle fish will make corresponding judgments according to transaction records and communication records between buyers and sellers, and assist buyers to refund.

However, it should be noted that the idle fish platform requires higher evidence provided by buyers. Therefore, buyers should keep relevant evidence, such as product photos and chat records, to prove their rights and interests.

Generally speaking, if the books purchased by buyers are pirated or pirated, they can report to the idle fish platform and apply for a refund. Idle fish will judge according to relevant regulations and evidence, and take corresponding measures to protect the rights and interests of buyers.
