Stripe records user movements on its customers' websites

For one, some definitions would be nice. How do you define "fraudulent payments"? If I tried to checkout while on VPN and firefox with resistfingerprinting enabled, and your antifraud system stopped me, did that count toward your "millions per day"?

We build models that predict P(payment charged back as 'fraudulent') and then let small random samples through in order to test the accuracy of our predictions. This calibration means that we can compute a pretty accurate "true" total from those we have blocked.

Out of curiosity, when a transactions is part of one of those random samples and is flagged as fraudulent, are the costs/impacts to the merchant the same as any other fraud chargeback/dispute (particularly those that don't use Stripe Chargeback Protection)?

The question was interesting. Too bad we did not get an answer here.
