Hi JackFr,
Jason here, op and CEO of Sift Science. You have a point, but do keep in mind that the TV is going to a bad customer -- one that won't reward Best Buy with repeat business (perhaps just more fraud) and won't spread positive word of mouth (except to let other fraudsters know that Best Buy is a great fraud target). So there is some "lose" in shipping the TV to a bad customer, different from shipping it to a good customer. Does that make sense?
