We got a couple cases of false positives ourselves, and I admit that the Stripe UI wasn't very clear on the fact that we couldn't override the "block" (even though the button was there, it didn't do anything).

That said, with a quick email to the Stripe support team, we got the transactions whitelisted in a matter of hours (I believe the Stripe support does regular US office hours, but that could have changed in the meantime).
