Ask HN: High Biases in Stripe-Radar?

5 pointsby saradhialmost 3 years ago
Following high (10.57%) USD-INR transaction fee on PayPal [1]. We, recently, implemented Stripe payments and found that the Stripe-Radar is hindering the subscriptions. Yesterday, we experienced 2-digit &quot;Blocked&quot; payments because of &quot;High Risk&quot;. I upgraded my account to see the reasoning, after evaluating the failures it seems the Stripe-Radar is highly biased to the distance between payment-session-ip-address and card-billing-address.<p>A card transaction with an 11-mile distance &amp; no history of frauds&#x2F;disputes has a RiskScore of 87. The transaction is blocked as the account by default comes with RiskScore threshold of 75.<p>There are &quot;Allow Rules&quot; on the Stripe-Radar, that are disabled as the account should meet 2K USD&#x2F;month. We have been consistently doing over 15K USD&#x2F;month on other gateways, and Stripe doesn&#x27;t want to consider the transactions statement to enable the option for new accounts.<p>Has anyone come across a similar situation? How did you handle it?<p>[1]. https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=32228267

Allow Rules, if not implemented properly, could open a vector for fraud. That&#x27;s why, for now, it&#x27;s not enabled for newer businesses on Stripe—and we ask businesses to contact support to turn it on manually (<a href="https:&#x2F;&#x2F;support.stripe.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;support.stripe.com&#x2F;</a>). Would you be able to get in touch with us? (Please CC me, edwin@stripe.com.) We&#x27;d also like to look into why these payments were blocked in the first place (distance between IP address and card address is not the sole factor for risk scores; there are many factors) and make sure future legitimate payments are accepted.
