Pull this post and talk to lawyers if you haven't already.
Depending on where you're based you'll have legal obligations that'll define what you should be doing at this point. This may well involve lawyers, your regulators and the police.
Some countries make it a criminal offence if you let a criminal know that you suspect them of money laundering or similar offences (this is known as "tipping off") so you should be very very careful about what you're disclosing both to your users and the general public.
Yeah, sorry, I wasn't clear: I'm pursuing openness because I believe in openness, not because I'm based in the US. I am glad to learn about this potential legal ramification, however.
If you tell people they're doing something illegal, they might stop before they're caught and sentenced to life in prison. And if we don't fill up the for-profit prisons, the lobbyist overlords won't be pleased.
