By "negative balance," we mean a negative amount for a currency with the status Confirmed.
Publishers working with the program AliExpress WW might encounter this problem.
If a publisher violated the rules of the AliExpress WW program, AliExpress can deduct an amount equivalent to the loss caused by the violation from the publisher's balance.
In order to be sure that there's not another reason for the negative balance, go to the section Balance history (Menu — Payments — Balance history). Read more about this section
In the filters, choose the currency in which you have a negative balance and the operation type Withdrawal. Apply the filters.
In the list, you'll see a withdrawal with the comment "AliExpress WW affiliate program. Antispam deduction"
If there are no withdrawals with that comment but your balance is negative, create a tech-support ticket.
If the balance in at least one of your currencies is negative, you will not be able to delete the account.
