PayPal Braintree for WooCommerce

As documented in https://wordpress.org/support/topic/thousands-of-posts-to-wc-ajaxcheckout-2/#post-16705941 and https://wordpress.org/support/topic/thousands-of-post-requests-to-wc-ajaxcheckout/page/2/ and in https://wordpress.org/support/topic/thousands-of-posts-to-wc-ajaxcheckout/

There is no prevention against credit card scammers testing tens of thousands of credit cards against Braintree using this plugin.

As a result of this I am seeing ~10k requests per day against a single checkout trying multiple cards. The result is tens of thousands of wp_comment records, slow server, warnings from Braintree and an angry merchant.

Your rep said there should be a fix soon over 2 years ago.

Now I am being asked to create a feature request.

Please fix your plugin. This is horrible.
