In response to these concerns, last year Yahoo came out with a system to verify people's identities and their correct email addresses and mobile phone contact numbers. It has also come up with a mutual evaluation system for buyers and sellers in order to build mutual trust. A seller gets one point for each successfully delivered sale; several sellers have already been honored with membership in the "Thousand Sale Club."
針對這些缺失，去年雅虎推出確認網友身分與正確聯絡方式的電子郵件和手機認證，也做出促進買賣雙方信任的評價制度，只要成功交易一次，賣方就可以得到一分積點，目前已有數位賣家榮登「千分俱樂部」會員。
