I would go down and independently verify if asked to with the only proviso being that I have absolute freedom to publicise what I find.
Highly doubt your offer will be accepted, because he will want his version published, not the truth.
How do we know this guy is a blatant liar? Well a lot of what he says cannot be proved or disproved as no independent people to verify. But some things he has said are patently untrue. For example he valued the stored boxes he had to burn at two hundred dollars a box. Even at brand spanking new they would be worth half that, and watching the video he himself posted of them being burned, most of them were poor shape and real value might be $30 or $40, IF they did not have AFB.
On one of his videos he was queried about the $200 per box valuation, and his reply was - well that's what they are on the books at. Does that mean he is also defrauding the tax department?
That, and some other obvious contradictions we know the guy is spinning a story and is disconnected from the truth.
One of the other horrible things is the people he owes money to are not speaking up, because they are hoping that one day they will be paid, but think if they speak up they will never be paid. This is an awful situation for people who are already on the brink of bankruptcy and no matter how hard they work they cannot support their families in the way they want. While Stephen is taking his family on world trips and not paying what he owes.
