Payment giants like Stripe, Braintree, and Adyen are in a constant arms race against automated bots. They have implemented advanced that identify the patterns used by checkers. If a specific SK key is used to rapidly test hundreds of cards, the gateway flags the activity and kills the key instantly—essentially "patching" the exploit. 2.
