The “invisible captcha” option sometimes doesn’t work against this type of card testing. This is pointed out by stripe here:
https://stripe.com/docs/card-testing
If you want to use the plugin in the future, use the “I am not a robot” captcha option. We have some explanation of it on the captcha configuration documentation here:
https://s-plugins.com/stripe-payments-recaptcha-addon/
I’d probably argue that the Invisible Recaptcha feature should be removed or at least come with a prominent warning in the user interface. I wouldn’t have used it if I had been aware of the issue.
While I appreciate the Recaptcha issue can likely be mitigated that doesn’t address the issue of the varied amounts and currency, that sounds like a flaw in the plugin.
