The problem of Amazon's cross-border e-commerce store automatically opening associations usually refers to the situation that when sellers use multiple accounts to operate stores, the Amazon system determines these accounts as associated accounts due to similar operations or information. Amazon has strict rules for store associations. Once an account is determined to be an associated account, it may lead to the store being banned or other serious consequences.

Here are some strategies to avoid automatic store associations:

1. **Comply with Amazon rules**:

- Ensure that the operation of each account complies with Amazon's rules and policies, and avoid using the same credit card, IP address, contact information, etc.

2. **Use dedicated devices**:

- Use independent devices and network connections for each account, and avoid logging in to multiple accounts on the same device.

3. **Separate operational activities**:

- Ensure that the operational activities of each account are carried out independently to avoid cross-operations.

4. **Unique brand and design**:

- Use unique brand, logo and packaging design to distinguish products from different accounts.

5. **Different payment and logistics information**:

- Use different payment methods and logistics services to avoid duplication of information.

6. **Check account status regularly**:

- Check the status of the account regularly to ensure there is no abnormal activity.

7. **Avoid using automated tools**:

- Avoid using automated tools and software that may cause store association.

8. **Legal operation**:

- Ensure that all business activities are legal and compliant, and avoid store association due to illegal operations.

If you have already encountered the problem of automatic store association, it is recommended to immediately stop all operations that may lead to association and contact Amazon customer service for help. When dealing with such problems, be sure to act with caution to avoid exacerbating the severity of the problem.
