This is one of the red flags for guys like Kashashy being crooks, or at the very least highly dodgy. Nobody really knows what they are worth, as their schemes and smokescreens can seem to inflate their wealth. Legitimate businessmen tend to have more easily checkable and reliable measurements of what they are worth.

I sometimes wonder about The Mirror. As somebody with some socialist leanings (believe it or not) I would be one of their natural target audience. But they don't have a great reputation for getting things right in my experience.
