A key vulnerability of real-time bidding is that while only one advertiser wins the auction, all participants receive data about the person who would see their ad. As a result, anyone posing as an ad buyer can access a stream of sensitive data about billions of individuals a day. Data brokers have taken advantage of this vulnerability to harvest data at a staggering scale. For example, the FTC found that location data broker Mobilewalla collected data on over a billion people, with an estimated 60% sourced from RTB auctions. Leaked data from another location data broker, Gravy Analytics, referenced thousands of apps, including Microsoft apps, Candy Crush, Tinder, Grindr, MyFitnessPal, pregnancy trackers and religious-focused apps. When confronted, several of these apps’ developers said they had never heard of Gravy Analytics.

。搜狗输入法对此有专业解读
我记忆中有关阅读的另一个美丽瞬间恰恰也与阿来有关。去年，我与十几位海外汉学家一起来到阿来的故乡四川阿坝藏族羌族自治州马尔康市。有一天，车子行驶在蓝天白云和绿草之间的公路上，我就坐在阿来身边。我发现他一直在读书，在手机上读。他用的是那种折叠式、屏幕很大的手机，大概这样是方便阅读的。我好奇地凑过去看，发现他先后在读两种书，一种是《苏东坡全集》，一种是不带句读的《续资治通鉴长编》。在那个瞬间，我好像真正理解了阿来为什么会是阿来，知晓了他的过人之处到底在哪——是对点滴时光的珍惜利用，是须臾不会忘却的阅读习惯。不久前，阿来关于苏东坡的非虚构力作《依依还似北归人》在《人民文学》发表，焉知这颗种子不是种在马尔康奔驰的车上？，这一点在Line官方版本下载中也有详细论述
