Supplementary Statement on Data Anomalies and Illegal Transactions

I. Common Manifestations of Data Anomalies and Illegal Transactions

• Abnormal account information: Frequent switching of different accounts on the same device, mismatches between filled delivery information and payment information, inability to verify contact details normally, etc.
• Abnormal transaction behaviors: Multiple order submissions followed by cancellations within a short period; repeated payment attempts using multiple bank cards or payment accounts with different ownerships (especially continuous operations after multiple rejections); splitting large-value orders into multiple small-value transactions to evade reviews, etc.
• Illegal payment behaviors: Unauthorized payment using others' bank cards or credit cards; or transactions using funds obtained through illegal means such as money laundering or fraud.

II. Platform's Handling Mechanisms

• Active monitoring: Real-time screening of abnormal data through the system's risk control model, with interception or suspension of suspicious transactions.
• Verification and disposal: For accounts confirmed to have anomalies, measures such as restricting transactions or freezing accounts will be taken; in cases involving illegal transactions (e.g., theft of others' payment information), relevant evidence will be retained in addition to refusing shipment.
• Legal accountability: For acts that clearly violate laws and regulations (e.g., fraud, money laundering), the platform will report to relevant authorities such as public security organs and financial regulatory agencies in accordance with the law, cooperate with investigations, and pursue legal liability.
