I've been thinking a bit abut trying out something different here. What I have in mind would be an alternative method that the user can opt for instead of the captcha (if flagged). It would be for those privacy people on Tor or Mullvad or what have you and will not compromise on privacy but may be a bit more techy/involve some form of crypto (no investments or new coins etc tho). So you'd still have the CAPTCHA of today but with an alternative. Assuming it's something that would seem to be a usable and smoother solution for those people you are today locking out or providing a hassle for without significant increase of malicious bots (maybe you'll even get less if it works all right and it means you can tune up the aggressiveness in the rest of the system), about how much willing would you be to try something out? (I'm aware of PrivacyPass but IME while I did have it work at times, most of the time it works extremely poorly to the point of being unusable on both Cloudflare and hCapctcha, while maintenance and support seem on the backburner)
