This is obviously a grey (or outright black) area which a lot of unethical people take advantage of, but you need to move quickly and then abandon the negative account, instead of sitting on a ticket that someone can notice and suspend.

Its obvious that the blogger did the whole buy something refundable to run up balance then book ticket with it shenanigans - they just weren't smart enough to fly before doing the refund.
