According to the rules of the Amazon platform, a store is opened by obtaining an account with one registration information.

If the store has only one account, the operation is relatively weak, so usually several accounts will be opened.

However, if multiple accounts are operated on the same computer, if Amazon's A9 algorithm finds that the store uses multiple accounts to distribute goods, it will directly warn or close the account, and the account information will be unusable.

So if you log in with an IP, one IP is equivalent to a computer, and operating one account can avoid account association and account closure
