Why you so stubborn on IP address? Its not a holy grail! I use proxy for some years now and many times I want to buy something on the frontstore “powered by Stripe” and my card is declined due to “unknow error”. Moment I turn off my vpn, transaction goes thru. I can exect this to be a huge problem for Stripe or anyone deciding on fraud attempt greatly basing it on IP. These days if i find a cool product and see “powered by Stripe” I simply end up on Amazon purchasing same product for similar price. Worst part — your clients don’t even know!

I’m sorry that you had this experience. We vehemently agree that any one signal (such as IP address or use of a proxy) is a pretty poor predictor of fraud in isolation. We are trying to move the industry towards holistic evaluation rather than inflexible blacklists; not everyone behind a TOR exit node is a fraudster, for example.

While we can’t fix the previous experience you had, we’ve rebuilt almost every component of our fraud detection stack over the past year. We’ve added hundreds of new signals to improve accuracy, each payment is now scored using thousands of signals, and we retrain models every day.

We hope these improvements will help. We want our customers to be able to provide you services; that’s what keeps the lights on here. We’d be happy to look into what happened if you have specific websites in mind—feel free to shoot me a note at [e-mail].
