If it were not obvous that you are bored, and decidedly not angry, and try to troll your way through support threads, it would be an interesting question.
What happens to the money, if payout cannot happen, because it was decided that the project was not owned by the account that sold it. I saw such a case of software piracy. It was a game and the same game was sold by a different account at a cheaper price.
My assumption would be, that refunds would have to be issued to the buyers. Or compensation would be due to the original owner. Some digging on search hints that this is basically what should happen in such cases. Refunds and should any be left, compensation to the original owner.
Cases where Itch would deny payout might be such cases. Indeed, some cases where Itch just takes ages to process the payout could be cases where allegations were made, but could not yet be decided.
