No clue what FUD or that person is. Where has what I said been disproven. It hadn't been. No one here has said how a PayPal gift from the balance can be reversed because it can't be said
I did some searches on google and found things which are very unclear from the point of view of reverse transaction , some say that they do have reverse stuff if you call the credit card issuer and do a charge back/Payment reversal.
Have a look to the thread:https://www.paypal-community.com/t5/Refunds-and-cancellations/Gift-payments-reversible/td-p/462611
