如题，最近10月3号因亚马逊Review新政策问题，这个词被好多人拿出来问。
 
Update on Customer Reviews
October 3, 2016  官方发布最新评价规定

Customer reviews are one of the most valuable tools we offer customers for making informed purchase decisions, and we work hard to make sure they are doing their job. In just the past year, we’ve improved review ratings by introducing a machine learned algorithm that gives more weight to newer, more helpful reviews; applying stricter criteria to qualify for the Amazon verified purchase badge; and suspending, banning or suing thousands of individuals for attempting to manipulate reviews.

Our community guidelines have always prohibited compensation for reviews, with an exception – reviewers could post a review in exchange for a free or discounted product as long as they disclosed that fact. These so-called ‘incentivized reviews’ make up only a tiny fraction of the tens of millions of reviews on Amazon, and when done carefully, they can be helpful to customers by providing a foundation of reviews for new or less well-known products.

Today, we updated the community guidelines to prohibit incentivized reviews unless they are facilitated through the Amazon Vine program. We launched Vine several years ago to carefully facilitate these kinds of reviews and have been happy with feedback from customers and vendors. Here’s how Vine works: Amazon – not the vendor or seller – identifies and invites trusted and helpful reviewers on Amazon to post opinions about new and pre-release products; we do not incentivize positive star ratings, attempt to influence the content of reviews, or even require a review to be written; and we limit the total number of Vine reviews that we display for each product. Vine has important controls in place and has proven to be especially valuable for getting early reviews on new products that have not yet been able to generate enough sales to have significant numbers of organic reviews. We also have ideas for how to continue to make Vine an even more useful program going forward. Details on that as we have them.

The above changes will apply to product categories other than books. We will continue to allow the age-old practice of providing advance review copies of books.

Thank you.

潜在说法就是：

不能使用第三方机构（比如fb小组测评，各大测评网站测评等）发出带折扣或者免费的产品给reviewer来换取评价；只有通过亚马逊VINE VOICE项目组的人来做折扣码或者送测，是合规的。通过其他人或者其他组织，即使在评论里声明了I received this product at a discount or free for review purposes 已经不被允许了！
此政策立刻生效！如果你继续用以前的方法免费或者折扣来换取评价，你的账号会被关；
你可以继续对客户发折扣或者一些促销，只要不是为了换取评价，都是可以的；
不许提供任何服务或者福利来换取评论。


第一点中提到的所谓亚马逊VINE VOICE项目组，是一个邀请制的GROUP（VINE REVIEWER GROUP），亚马逊对于诚信度高的买家采取邀请入驻来做测评。这个团队他们一般逼格比较高、优先做直营产品的送测。做VE的小伙伴应该不难理解。VINE VOICE的review相对普通的review权重会更高，每条review都会有vine voice的标志。
