The penalty cycle for Doudian violations depends on the specific violations and the standards of the industry. Generally speaking, the penalty cycle for Doudian violations may include the following stages:

1. Discovery stage: The Doudian platform will monitor and discover the user's violations and send warnings or reminders to the violating stores.

2. Processing stage: The Doudian platform will punish the violating stores according to the rules, which may include limiting store exposure, reducing store weight, limiting store sales, collecting fines, etc.

3. Rectification stage: If the violating store can actively cooperate with the rectification requirements of the Doudian platform, the penalty may be cancelled or reduced.

4. Review stage: If the rectification stage is ineffective, the Doudian platform may require the violating store to review and may need to provide more evidence to confirm the violation.

5. End stage: If the violating store still fails to correct after the review, the Doudian platform may end its cooperation with it and delete the relevant violation information.

It should be noted that the standards and cycles for penalty for violations in different industries may vary. It is recommended to understand the relevant rules of your industry in order to better comply with the platform regulations.
