Who decides my address is bad and how?
The companies who earn money from selling their taint-detection-services of course! They're also the ones who have all financial interests in promoting the crazy idea that taint even exists, because without it, they'd be out of business.
We analyze transactions to addresses that are in our blocklist. In this blocklist, we add addresses that are transmitted by our partners (other exchanges and services) who are aware of the facts of fraud and theft, as well as from victims who come to us with a statement that their funds were stolen.
This sounds awfully arbitrary. Can you start by publishing your "blocklist", so customers can check if their addresses are on it before sending their funds to your exchange?
