I got a 90% change of being human using recaptcha v3.
1. What percentage would you consider appropriate for humans?
2. What percentage do you think recaptcha v2 is actually using?
3. Suppose you a user is trying to register to your site and gets the value from the answer to question #1 minus 10%. What would you do with that user?
4. Can you provide a link to a piece of documentation that states that v3 is actually "stronger" than v2?
