All of these may result in you bringing in less $ overall, so it really depends on how much each fraud case costs you, but you could (off the top of my head): - Enable always checking CVV - Require 3DS - Ban a card after N disputes - Ban an email/other identifier after N disputes - Ban certain payment methods, banks etc - Add a visible or invisible captcha to fight automated abuse/card testing

I suspect Stripe walks a fine line where they want to help you prevent fraud, but they also want to avoid vendors complaining to them that their customers can’t pay.

Context: I worked on a payments team for a short while.
