I understand and respect the need for privacy of someone OWN HARD EARNED MONEY, but when/if you know that scammers and cybercriminals use your service it would be better to report their trades back to the police requests.
Scammers and Criminals bring no good to our world.
In my humble opinion, the principle of a service focused on respecting the privacy and data of its users, is precisely that it doesn't arbitrarily choose to whom it offers privacy or not.
