I know, I know, "bounties" are a fraught concept. Some people find "snitching" odious. But this is a tantalizing use case. All the author of this piece got out of their legwork was another article, but it also yielded some money for the federal government:

> Two days after I emailed Finwall in April inquiring about the Xie Foundation’s purchase of the house, the foundation filed records with the California attorney general’s office, stating that it had “discovered a self-dealing event” and including a federal tax return with the word “amended” handwritten at the top. In his email to ProPublica, Finwall said that, after amending its returns, the foundation “paid some excise taxes related to Mr. Xie’s stay at the property.”

Maybe we can give 1% of the recovered tax to forensic accountant bounty hunters willing to vet the appropriate nonprofit filings. As is, the IRS seems under-resourced for this kind of work, and there's no real incentive for anybody else to do it unless they're a journalist -- and you can only write this kind of story so many times. Maybe each submitted case costs $100 or some other fee sufficient to deter spammers. I strongly suspect there's a class of feisty semi-retired accountants who'd be happy to spend some of their golden years on this kind of thing. If we're worried about small nonprofits, we can set a minimum claimed deduction that's subject to a bounty.
