An electronic commerce system and method for managing sale and distribution of products over the Internet or other type of network is disclosed. In order to prevent attempts by users to fraudulently obtain the products, the system analyzes during an electronic commerce transaction the user-entered information entered by the users into the end user machine in connection with an electronic purchase order for a product to determine a fraud ranking. This fraud ranking indicates a likelihood that the order is attempted fraud based upon a quantitative analysis of a daily bad uses counter by determining a number of times that a piece of received user-entered information from the electronic purchase order appeared on another order that was declined that day. Based upon the determination, the system accepts or declines the order. The system also saves the user-entered information for use in determining whether to accept to decline future orders.
