Donations used for mass card testing

Hi, a site that I work with is experiencing a lot of card testing issues where people are using the donation area of the site to test if their card numbers are working. One of them did 80 some (failed) transactions in just a matter of minutes, so clearly they are automating the process. We're using a reputable WP donation plugin on the front-end of the site and using Brain Tree as a payment processor which is using basic fraud tools. None of the transactions are being accepted, but it would still be great to block them somehow. Any advice on stopping these?

put hCaptcha on the page and verify the user or test if their IP is listed here before sending the request to the card processor,
