Humanmark for Discourse - Hardware-Backed Humanity Verification

This is interesting. I have a question, will this prevent banned users from re-joining the community? For example:

  1. Notorious troublemaker, keeps signing up
  2. Joins again, passes Humanmark
  3. Gets banned
  4. Joins again
  5. Using the same hardware, will he or will he not pass the verification under a new account?

Is theree a demo we can see somewhere?
