I'm in favor of privacy, but if you're profiting off designing and operating a system that you know is being used to facilitate large amounts of criminal money laundering (some going to known foreign government agents), you're more or less asking to be arrested.

You can pose an argument that your service has some positive impact in certain cases, but you can't flat deny any negative impact or responsibility for consequences of your service. This is true of any and all services, whether they relate to privacy or not.
