I just tried an address, and the results were completely different. One returned low risk, while the other was medium (almost high) risk. I would also be very interested in knowing what is the returned results for people who actively use mixers or non KYC platforms.
It doesn't matter what risk score you received, but what score was calculated by the service you are sending coins to.
Mixers like Mixtum give a very low risk score of 5-20%
At the same time, funds from no-KYC exchanges are often classified as medium risk because they are recognized as originating from an unlicensed exchange. Although traditional CEX doesn't pose a problem with receiving it. At least I haven't had such an experience.
