Whale is a gambling term. Which shows exactly what was happening here, Facebook (and yes, a lot of the gaming industry) provides gambling to kids. It should be illegal. And no, you won't shame me into not being outraged by it.
Yeah I'm sure the employee in question used the term explicitly because he or she gets off on corrupting 5 yr old brains as a hobby.
OR
It might have been a quick reaction to the exorbitant expenditure and it was the first word that occurred to the employee because it's a common term and they've dealt with 50 other cases that day.
