Most fraud detection systems rely on blocking rules. So they'd detect a VPN/Tor and combined with an international order, it'd be an almost guaranteed block.
We'd factor this in, and it may be negative, but if the other 198 variables match up, you'll be in good shape with Bolt given your purchase behavior, on-page event patters, order details, and many other factors that are much better predictors of fraud than VPN/Country/etc.
- huhtenberg 9y ago> other 198 variables match up With what exactly? 198 variables will be the same between two cases I described. The follow up question is what your false-positive rates are. As I said in another reply - there is a set of simple and common cases when both fraud and legit purchases look the same, so by having a zero fraud rate you will be driving the false-positive rate up - and that is bad. People won't be able to pay even though they are already with a wallet in hand. This in turn means that merchants will need to implement a fallback option to cover this risk... which is going to be PayPal, probably. All of this is why Stripe Radar implements _provisional_ blocking. They let purchases through, but flag them for a human review. I am going to make a bold prediction and say that you will converge to the same approach sooner rather later. There's no magic recipe.
- rbres 9y agoWe never auto-reject, and we already do human review. Forgot to mention that. At the bottom of https://bolt.com/fraud https://bolt.com/fraud "MACHINE POWERED, HUMAN REVIEWED" "Everything we do at Bolt is tailored to maximize your order approval rates. Purely algorithmic systems falsely reject good customers. Every suspicious order goes through an extra layer of human review to ensure the best results."
