$12, one audit at a time

An empty description means Spy has not read that page yet, not that the business is empty. Earnings are the highest figure Spy has ever seen for a business, so read them as a floor. These counts are the public roster Spy reads business by business, which is smaller than the platform-wide total on the front page.
