This sort of thing is not reported. Ask yourself: if you had a business disagreement, could you reach out to a good friend and get the other side thrown in prison for years? You have no particular reason to believe me, but I have seen a similar situation play out for a friend of the family. This is a person of spotless ethics, who had never done anything untoward in business, but who nonetheless was entrapped into a federal conviction and loss of career.

If the word "Yalincak" doesn't appear on the page "List of Ponzi schemes", it seems problematic to redirect his name to that page. This implies something while offering no evidence for that implication. The discussion you link seems to imply that the oft-cited New York Magazine article was retracted, but I can find no proof of that.

You said NPR is "omitting the certain fact that Ervine paid this "friend" tens of thousands of dollars", then offer no proof and say "This sort of thing is not reported". It's not really a certain fact then, is it? It's just your assumption.

Mention of Yalincak was removed by an anonymous editor in March 2015:

Edit summary for this change was "added a hyphen and fixed a grammatical error". Hmmmm.
