It&#x27;s hard to say, Stripe (or any other merchant account) may be blocking some charges, but you really don&#x27;t have visibility into why a charge was blocked.<p>Regardless if they are blocking a lot or a little, they all let way too many fishy charges go through. They are just not incentivized to police fraud because in e-commerce its <i>you</i> who are on the hook for the charge back, not the bank or credit card company.<p>You cannot rely on your merchant bank (Stripe or anyone else) to do your fraud protection. You will get eaten alive.
