If I was an american I would honestly file a complaint to the IRS for suspicion of fraud. He claims he has people working for him, his revenue from Patreon is public, more revenue comes from his site clearly, another chunk of money could come to him directly so it seems that he is really busy.
He must have a company to do all of this so a competent authority on this matter would clear all this suspicion up in no time. There have been a whole lot of cases of fraud discovered on Kickstarter and similar sites for crowd-funding, on Youtube, on donation sites and even on Patreon.
Some people are in jail for this kind of thing, others have to pay so much money back that even their children will have to contribute and the ones who done the time and payed for the crime are left with the public disgrace that comes with this.
I don't live in the USA but some people do, just saying.
