I keep complaining that Amazon’s recommendation algorithm stinks but it turns out that they are using all their data mining experience and personnel to battle out-of-this-world theft and fraud. There are people whose only pursuit in life is defrauding Amazon. They create thousands of accounts each and engage in all sorts of inventive fraud. And theft in warehouses is ridiculous.
For such an enormous organization, the only way to make it work like clockwork for the customers is to allow extreme chaos on the inside. And chaos is where fraud breeds.
I guess I won’t complain about recommendations any more.
