It would be hilarious until Paypal decides to file fraud charges to make an example of you to send a clear message to anybody who thinks it's fun to embarrass them.

this is why you'd be the person scammed and would want the refund.. the other scamming party is the one that sends the screenshots, this is the party that paypal would go after

...but you need someone to play the role of the scammer. That's what the parent was offering:

"I should totally provide them screenshots showing that I just sold their domain out from under them."
