I agree, the member in question has probably earned from ads, grid wins along with task.
I do get 7,14, and 24 cent task (twitter ones) in the morning (they go fast) but they add up fast as well. Along with the weekly task that come in everyday that are worth 7 to 14cent task add up very fast as well.
Not sure if this helps you.
