So is it really better to let people continue to be scammed in the name of silence to prevent scammers from learning the scam? If this is something truly unique, and I have my doubts, I think you should explain the process here to prevent additional scams. The community has enough outlets to get the word out and prevent many more additional victims. Of course, people get scammed everyday anyway by the old scams, but if it's a particularly novel approach, most people will find out before it happens. Forewarned is forearmed.
