How did you contact them to let them know?? You are the scammer and I can tell from the way you use the English languageon the link you provided.
"They have stolen over USD 10,000,000.00 from hard working US citizens. Spread the word as viral as possible so that they could be caught." I recognize the use of the english language as the same style that the scammers used in my messages they sent to me. You also said "Report them at authorities" You need to stop scamming people and I am going to help you.
