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.
can't say for mixers, but i tried with an address that received payments from gambling sites, and the results were conflicting as you can see.
All of this tools work in similar way and they can never provide precise information.
eeny meeny miny moe, is the address risky or no? you don't know? just generate a random score for the answer.that's the "algorithm" they use, it's all bs.
It's more concerning for me that so many people actually trust this silly aml risk scores
