Thanks for recommending Buster (author here), but I think the right solution is to encourage people to stand up against Google's abuse, especially because they are working on making reCAPTCHA even more pervasive an inescapable.

The recommended way of integrating reCAPTCHA v3 is to load it on every page of your site, not just on pages with forms. Given the popularity of this service, reCAPTCHA v3 is set to become a browsing history and behavioral data collector on a global scale.
