WidgetBucks removed $6 from my revenue( in red)

Many curiosity about www.WidgetBucks.com (referral id added).
An hour ago when I looked into my account, it was $16.5, revenue in red and waiting for audit.
Now, it is $10.10.
I’m sure it was $16.5, because I told it to my friend when I looked into my account.
What happend? Anyone has this experience?
