Is it?
Those people/farms book bunch of refundable first class tickets on the airline / miles credit cards, manufacturing hundreds of thousands of points. Then they sell those miles accounts to another party who books airline tickets on them. Then the spending that was manufactured gets refunded causing the credit card / frequent flier accounts go into a negative miles balance. This causes the credit company a financial loss, as they provided 100,000s of miles on spending that was later refunded. Then the party that purchased those points from the"farm" also gets screwed as the airline cancels the tickets, when they realize it was refundable spend. Can anybody explain why this is not ganeiva and not a chilul hashem?
Not to mention when they farms sell the points, they do not disclose that they used refundable spend to manufacture the points, and lie that the accounts are crystal clear with no shtick.
