"Inactive accounts have up to 180 days (~6 months) to request a refund for any purchased credits remaining on the account. After this time the credits will become void and cannot be refunded. Eligible refunds will only be processed once we have been assured of your identity.
For example:
If you register an account on the site and purchase AW Credits, then subsequently do not login for over 12 months, your account will automatically be deactivated by us. From that point of deactivation, which you will be notified of by email, you have 180 days to either request a refund to your card or transfer the credits to a new registration."

So unless the lock-down is going on waaay longer than expected, it shouldn't be an issue I'd say.
