Moreover, the Fatwallet example just smells like a fake. The guy is a "millionaire" who cannot type a complete sentence and has so many inconsistencies in his story, he makes James Frey look legit.

I often find these reports suspect. It isn't that there aren't real account closings by Chase, but those reporting such closures rarely want to admit any fault or culpability and simply omit any facts or information that might paint them in negative light or explain the real reasons behind Chase's decisions. And so we're here left to hypothesize based on incomplete information.

I'd say keep it simple: Don't try and scam Chase and you're probably going to be safe.
