I agree with you guys that fungibility is one of the fundamental properties of bitcoin but, unfortunately, CEXs think otherwise. So, such a tool can indeed be helpful for those who have no other option but to use CEXs.
That's the point.
We don't like taint and believe that all bitcoins are equal. However,
they will give you all kinds of trouble if your coins AML score are higher than a certain threshold.
If you don't believe me, just open any exchanger on Bestchange and see for yourself.
Even if you don't believe in taint, you need to know what the AML score for your addresses are, because without this information, the exchange could report you and you
could get into trouble even though you did not even do anything. You can't walk blindly and deprive yourselves of this information.
It's important to note (hmmm... ChatGPT-like ending eh) that running your coins through a mixer or any sort of coinjoin will completely destroy the traces of origin and will in most cases keep the AML score low enough that smaller exchanges and other services won't bother you.
On a separate note, I would like to know what system OP is using to get these scores from. For sure it is not in-house. Such things don't exist. Telegram AMLbot is the only cheap scoring service I am aware of.
Also, I would like to report one complaint.
In order to get a detailed breakdown, I have to enter my email address in order to get info about my address. This inexplicably ties my email i.e. identity to my address. Why? It's not necessary. Just post the report directly in the site with the option to download it if you want. But don't require email to received detailed reports.
