Understand Amazon's Requirements: Amazon allows multiple accounts for legitimate business needs, like different brands or product lines. However, avoid obvious associations between accounts to prevent suspension.
Use Multi-Accounting Browsers: Tools like MoreLogin allow you to manage multiple accounts with unique digital fingerprints (IP, device, cookies, browser fingerprints). This helps in appearing as separate, unrelated users to Amazon.
Proxy Servers: While not foolproof, proxies can provide different IP addresses for each account. Remember, Amazon's advanced tracking can sometimes bypass basic proxies.
