I'm over-simplifying "fraud signal" here, but it's a component of one of our payment provider's signal, mostly around "friendly fraud" where people might just have lots of overdue payments or not be responding to payment requests. It's less about signal about addresses and more about the same address being re-used on multiple stores. Edit: being super clear... The payment method is a pay-later service, it's literally a loan. The email is used to look up to see if the person has paid their loan balances off late before and other factors like that. "Fraud" was probably the wrong term to use here.
