亚马逊前一段时间为了保持评价系统的真实性，姐夫不惜得罪他的客户——大规模封杀掉了配合卖家刷评价的买家账号。
对此，亿恩文章《一下封了上千买家帐号！亚马逊这次开刀意在……》指出亚马逊面临的困境包括被特朗普一周5次狂怼，这次又面临社交平台上买家集结组团抗议亚马逊封杀买家账号。
此后据不少卖家评估，亚马逊此次行动不止封杀了上千，这个数字甚至达到了十多万。
一套干净利落的组合拳打下来之后，亚马逊也只淡淡的发表了几句话的声明：已经对行为不良和违反社区准则的人采取了行动……
记得姐夫有一句名言：善良比聪明更加重要……
此外亚马逊对外也一直宣传的是自己平台上存在的买家反馈都是真实的。
封杀了10多万行为不良买家账号后，亚马逊又对买家留评权限进行了限制
上图是最近几天在卖家群内被炒热的话题，亚马逊最新贴出买家留评条件如下：
Note: Additional guidelines applyto CustomerReviews.

核心内容与改变包括两点：
一、付费会员留评权限更大
二、过去12个月采用信用卡或者借记卡产生的消费才能留评
亚马逊一般会从以下五个方面判断买家账号是否操纵评论：
1、动态留评率的平均值：如果这些所购买的listing的留评率高，就被定义为操纵评价
2、访问购买比：访问量是实际订单量不成比例
3、 购买类目的分散度：买家账号购买的listing的类目过于集中也会影响到评价是否会被删
4、买家账号平均留评星级：连续5星和长期在4星以上留评星级必然会影响到listing
5、付款方式：即信用卡占比（礼品卡不是不可以，但信用卡一定是占大比重）
加上最新添加的留评条件2，卖家养买家号进行操控评论的门槛会有很大提升，这也就是为什幺会有卖家说刷单将会变得越来越难，产品为王的时代进一步来临。
