It is quite interesting to do something like this, even after giving KYC information. This means two things, either they are at a place where it would be very hard to find them and sue them, some places do not have law agreements with other nations, so only the citizens of that nation could sue you (or just people who live there) so maybe they trusted that? I have no idea to be fair. Or they just feel like they will not get in trouble at all, like maybe used someone else's info they found online, or they just did something else. In any case, they must feel like they have a thing in their hands that protects them, otherwise its silly to have all your information and ID all over internet and be ok wit hit just for 3.5 million dollars. Sure that is a lot of money, but what good does money can do when you are in jail?
