Anyone who's worked in gaming knows that "Whale" is a term to refer to high spenders that are several deviations from the norm.
A 1-year old racked up $10k in bills on a game where people normally spend $30? Whale. Period.
That's not unreasonable at all because the 1-yr old is in-fact a high spender several deviations from the norm.
Does any of this mean the game was explicitly marketed to 1-year olds? No.
Is it possible that the parent racked up the $10k in bills and blamed it on their kid? Entirely.
Have at it HN.
