Why does flydubai restrict payment for travel to certain countries?

Following on from this answer where it is reported that flydubai will not allow someone to purchase a ticket to Bangladesh, Ethiopia, Nepal, Pakistan, Sri Lanka or Sudan for another person via credit/debit card.

Just out of curiousity... why is that? I'm guessing it has something to do with foreign workers in the middle east, since they seem to be specifying countries from which large numbers of workers migrate, but is there a significantly higher risk of credit card fraud from these countries?
