No other seller comes close to this 1 million positive feedback milestone

NEW YORK - If you've ever sold something on eBay, you may have been pleased to receive positive feedback from the buyer. Multiply that by a million, and you can imagine how Jack Sheng feels.
Sheng, 33, owns Los Angeles-based Eforcity Corp., which has been selling electronics accessories on the online auction site since he started his business in 2000 with two childhood friends. In the past two months, four separate eBay user IDs belonging to Sheng and his company each surpassed more than 1 million feedback points. No one else on eBay has come close.

It should be noted that the four sites (> 4,000,000 total + feedbacks) does require the employment of approximately 200 people; so it's really a pretty big business. I don't know that there's much significance to "20,000 positives per employee" but it's another way of looking at it.
The article says second place goes to someone with a mere 750,000 points - a CD/DVD distributor.
