ReCaptcha scores are measured on a spectrum ranging from 0.1 (the worst) to 0.9 (the best).
Some factors that come into play when assessing an accounts ReCaptcha V3 score include:
IP Address: Yeezy Supply and Adidas determine whether or not you are using a trusted IP. If your IP/proxy is flagged you will not have a trusted score.
Account: Your account usage patterns are also taken into account when determining your V3 score and play a crucial role in your ability to pass splash using Phantom.
Site Security: Site security plays a crucial role in determining your V3 score. It is important to note that although V3 test sites may return a 0.9 score it does not guarantee that you will have the same score when accessing Yeezy Supply and Adidas.
