No, the guys at fraudulent labs and the guys at honest labs will both claim no fraud. The only ones who will claim fraud are those who cross over. So you’ll get a vast majority telling you it’s not happening and a tiny minority (even when as high as 10% are fraud) telling you the fact. All rare things have this effect. There will be so many people telling you it’s not real “as someone in the field”. They will be adamant about it. You need someone who has seen both.

To be clear, not “as it approaches 10%”. I mean “even as high as 10%”.
