How to refund minecraft donations from paypal?

You can't sorry:/

LOL, indian giver.

You can't. You made the donation, and if more than 24 hours has passed you can't legally get it refunded.

Sorry, but its the server policy on whether you get the money back. If they say no (in which they probable will), there's nothing you can do to stop them. Plus, why would you want your money back if you donated it. It's like donating to the red cross then later saying "Hay I want my money back"! But they won't give it back since it was a donation. I'm sorry man, but I guess you have to suck it up because you ain't getting it back.
