Part of this type of con is to make sure that no one else knows that you were given money. Without a trace if possible.
The less evidence there is that you were given money, the more likely you avoid prosecution.
Also, everyone heard you say it is your own money and you didn’t want their money.
Makes a nice defense in court with lots of witnesses for you to call.
How do you get someone's money without them knowing it? Isn't that simple theft, and not a fraud, if you take someone's money surreptitiously, without their knowledge?
