Social ads on Facebook are supposed to be cheap. In fact, they are one of the cheapest ads on the Web in terms of cost per thousand impressions. So imagine Facebook advertiser Joshua Niamehr's surprise when he logged into his Facebook ad campaign and saw the following notice: There is an outstanding balance of $8,804,978.14 USD on your account. Your ads will not be displayed until your account is settled. Please enter a valid funding source. When you submit that information, we will charge your funding source for $8,804,978.14 USD. Needless to say, he did not click "Make Payment." Niamehr's credit card had expired, which is why his account was delinquent. But his actual outstanding balance was $58.07, not $8,804,978.14. (He was placing ads to market his site LaundryLocal ).
