In fairness, anyone trying to convince me of any given fact of authorship could do well by leaving the bright red shirt and braces combo in the wardrobe.
Like wtf is going on.
The fact that his actions don't actually look much like the rich, a supergenuis, or an entrepreneur doesn't matter-- the target is people that don't actually know what that looks like.
It's the same reason that he claims to have earned more than 20 postgraduate degrees in the last three years alone. People with the relevant experience recognize that claim a lie or an admission of an unproductive mentally ill degree hoarding fake. But to his targets it signifies him as brilliant beyond any judgement or comparison, such that any red flag gets dismissed as an understandable quirk of a truly singular figure.
But I think more than anything, the stuff he does would convince him. Write what you know, you know?
Having a number of people thoroughly convinced seems to be a key to getting others who might otherwise know better to fail to apply their judgement.
And if its stupid but it works, it's not stupid. :-/
I dont know tbh
