To be honest, I am the first to hear about all of the above names.
If everything you say is really true, then it would be good to provide as much evidence as possible saying that these people have committed a crime.
One way or another, they may be subject to the sanctions of some countries if their crimes are proven. $ 15,000,000 is a very large amount.
I believe lindstromaka and another forum member has tried the legal way. But it doesnt seem like they got very far..
