Stripe banned us for payment disputes but we never had a single dispute

(Stripe cofounder.)

Ugh, apologies. Something very clearly went wrong here and we’re already investigating.

Zooming out, a few broader comments:

* Unlike most services, Stripe can easily lose very large amounts of money on individual accounts, and thousands of people try to do so every day. We are de facto running a big bug bounty/incentive program for evading our fraudulent user detection systems.

* Errors like these happen, which we hate, and we take every single false rejection that we discover seriously, knowing that there’s another founder at the other end of the line. We try to make it easy to get in touch with the humans at Stripe, me included, to maximize the number that we discover and the speed with which we get to remedy them.

* When these mistaken rejections happen, it’s usually because the business (inadvertently) clusters strongly with behavior that fraudulent users tend to engage in. Seeking to cloak spending and using virtual cards to mask activity is a common fraudulent pattern. Of course, there are very legitimate reasons to want to do this too (as this case demonstrates).

* We actually have an ongoing project to reduce the occurrence of these mistaken rejections by 90% by the end of this year. I think we’ll succeed at it. (They’re already down 50% since earlier this year.)

More important than that is provide a way for people to get this revolved without having to make the front page of HN.

One particularly frustrating aspect of fraud prevention is that fraudsters are better than the rest of us at getting human support staff to do what they want. They have way more practice, and they learn techniques that work from other fraudsters.

Right. It's a hard problem. That said, we think we can get better.

Reading the stories week in and week out, we think you can get better, too.

Hopefully that's a more diplomatic version of my (somewhat valid) sibling comment.
