昨晚评论席互动的时候聊到了网络实名制，我说起点是2013年，很多读者没概念，我说具体一点，最重要的措施是2013年9月1日施 行的《 电话用户真 实身份信息登记规定 》。 在这之前普通人可以随意购买电话卡，不用绑定个人信息，这既意味着可以匿名电话，也意味着可以匿名上网，因为上网的前置基础是电 话卡。电话卡实名登记后，互联网上的所有行为，本质上都可以定位到具体的个人。 我读高中、大学那会，去网吧交钱就给开机，后来才有了必须登记身份证这一环节，也是为了互联网行为穿透到个人。不然你在网吧上网 乱讲话，到时候警察查过来网吧老板吃不了兜着走。 至于全面落实网络实名制还要再晚两年，到了2015年3月互联网所有平台账号都落实实名制，从那以后你想给别人的评论点个赞，都要验 证过手机号才行。 至于读者留言说就算有了实名制，很多网民还是浑身戾气。那是因为这些人知道谁能开盒他，有戾气也要憋着，至于网民和网民之间没有 开盒的威胁，人性的阴暗面根本不用装 …… 今天a股成交1.19万亿，量能比昨天少少反弹了一些，今天小微盘股的表现不佳，个股中位数-0.63%，正好把昨天的+0.63%又跌了回 去。今天涨最好的还是化学原料+2.9%，这 ...
