Amazon says it will start capping the number of product reviews any customer can submit in a given week, limiting each person to five/week except for products that have been verified by the company as purchased by the reviewer. From a GeekWire report: Books, music and video are exempt from the limit, but the new cap applies to the rest of Amazon's vast online selection of products. It's the latest move by the e-commerce giant to police its online reviews, a critical resource used by many online shoppers to assess products before buying. The news comes during the peak holiday shopping season, the most important time of year for Amazon, as the company tries to get more people comfortable with doing more of their shopping online. An Amazon spokeswoman confirmed the changes in a message to GeekWire, and they're spelled out in Amazon's updated Community Guidelines.
