As I understood it, this was Null's experiment to see if he could instill some work ethic in Chris. If this ends with Chris getting burnt (again) and not being paid for his work, he's going to continue not working in the future.
Commissions and shoutouts were completed as promised, so let the motherfucker keep what the motherfucker worked for. Give refunds to people who donated under $40 or haven't received their commission yet, but if they got something in return for their money, then they're SOL.
IANAL obviously, and I look forward to hearing GoFundMe's opinion.
