Bought 2 servers, paid combined USPS shipping for one. Item weighed over 70 lb USPS limit. Offered to refund his money immediately. He said ship UPS instead. Advised him that UPS would cost more. He leaves a negative about how long it took to ship (he received item in 3 days from when he paid), and then says he will remove it if I give him a refund of UPS fees. Feedback extortion. Added his name here, and submit his email and address for doxing.
