本文是将我发在 Steem 上的两篇帖子 Steemit 的新手们，你们考虑过数据隐私的问题吗 和 开发了一个易用的在线小工具 steemr 合在一起重新编写的。读过这两篇的就不必再读了。
Steemit，新生事物，最近因为土木坛子晒钱包，大家看到之后纷纷眼热，于是蜂拥而至。不知用户有没有意识到自己在 Steem 上的个人隐私问题。要知道，用户在 Steem 上的一举一动，都是记录在案的。有人说，在互联网上没有隐私可言，什么都查得到。但是我认为 Steem 不一样。比如我想知道你的微信或 QQ 账号有哪些好友，你最喜欢跟谁聊天，你一般几点钟最活跃，这些数据虽然在腾讯服务器上，但是我获取不了。而 Steem 上的这些数据，是对所有人开放的，只要别人想，就可以得到。
那么，别人到底能看见你的哪些信息呢？
下面，经土木坛子允许，我们用他的账号 @tumutanzi 的公开数据(https://steemdb.com/, 采集时间 2017-07-26 22:06:46 CEST)，进行一点粗浅的展示，所用的工具是 R 语言。数据处理得比较仓促，连分析都算不上，如有错误，抱歉得很，请先原谅我，然后指正。
@tumutanzi 的粉丝有 319个ID，按照受欢迎程度（即他们各自被多少ID关注）排序的词云是这样的：
凡是看得清的，基本我都不认识。 @abit 大神在这里并不起眼。
按照发帖数排序是这样的：
@abit 和 @oflyhigh 两位大神似乎也并不显山露水。
按Vest（是什么？富有程度？）排序是这样的：
吓死人了。 @abit，拥有 4077000000 Vests，鹤立鸡群，弄得别的ID都区分不出来了。这叫闷声发大财么？
我们把他踢出去再看看：
@oflyhigh 和 @xiaohui 现身了。
另一方面，我们看看 @tumutanzi 都关注了谁。
@tumutanzi 关注的ID总数是 305（包含后来他取消关注的）。其中，有152个 ID 跟 @tumutanzi 是双向关注的，而153个ID 虽然被他关注，但却没有关注他。奈何明月照沟渠。可怜的 @tumutanzi，这些不搭理他的 ID 是：

奇怪， @abit 和 @justyy 明明在 @tumutanzi Steemit 的 following 名单里，但是在 steemdb 里却没有.
Steem 上任何 ID 的类似信息都可以轻易查到。为此，我开发了一个在线工具 steemr，方便那些不懂编程或懒得编程的朋友来查询 Steem 信息。查查自己的，查查别人的，想查谁就查谁吧，出了事儿别找我。
steemr 用起来很简单：
点击
Follower report标签，输入你想查的 ID，点击GO按钮，等几秒钟或十几秒钟（取决于服务器的速度和 你要查的 ID 的情况）就可以看到结果了，包括粉丝 （followers） ID 的词云图，按这些粉丝的粉丝数量、发帖数量和vests大小排序。如果粉丝超过30个，就取前三十个。词云图下方，还给出了尚未互粉的 ID 列表。点击
Voter report标签，输入你想查的帖子链接（可以是完整链接，也可以是从@符号开头到末尾），点击GO按钮，等几秒钟或十几秒钟，就可以看到为该帖点赞的名单和百分比。图下面给出了尚未投票的粉丝名单（类似的工具有 @justyy 的网页界面 ， @beautifulbella 的Excel 方法， @oflyhigh 的Python 方法）。
本工具以后会进一步开发完善。这只是冰山的一角。
再次提醒大家：在 steemit 发文发照片要三思，发布之前多想想，免得后悔。在区块链上，水一旦泼出去，就再也收不回来了。
