I realize that you probably have no clue how this sounds, so I'm going to translate this sentence into how it sounds to those of us outside the crypto world:
> Both the scammers-of-normal-people and the scammers-of-the-scammers have no references because their clients are all scammers who don't want their marks to know that it's a scam
Please do correct me if I'm somehow misinterpreting the reason why it is so important to these "legit" contacts that secrecy be maintained lest their "community" find out.
