互联网撸羊毛的万恶之源：手机黑卡
前几年有间新的互联网直播平台发布鼓励政策，只要你注册了这个直播，就能给20块钱，直播半个小时就给10块钱，直播两个小时给40块钱，如果看你直播的人多，还有排位奖!有些主播用单个账号主播，然后注册小号领钱直播，然后小号再去互相刷礼物，赚取排位奖，一天收入数万元。这个消息在各个消息群，撸羊毛群里疯传。
过程不讲了，直接说结果： 根据统计机构的数字，实际上这个直播软件的真实用户才 112 万，与其投入的 16 亿资金极其不成比例，净亏损约 10 亿元，仅仅主播分成就达到了近 14 亿，其中不知道有多少被僵尸军团撸走了。
与之相对应的是：某某软件刷排名、刷礼物、身份认证套装等等黑料，在暗网中猖獗一时，黑产届多了许多日入数万的百万富翁。
想来，这间公司只看到了直播软件的火爆，看到物质刺激可以吸引流量，没有深入研究黑产背后的东西。 随着国家对手机号实名制的大力推行，很多公司加大了对手机号的依赖，找回密码、身份认证、修改密码、大额支付等等，均需要手机号的参与。
一旦手机号这个环节出了问题，无论你的风控体系如何完善，都会出现意想不到的后果。
更何况，有些电商公司的高层管理者只有传统金融风控背景，对互联网账号业务的安全风险估计不足，导致其开展新业务、活动运营、新用户注册等的时候，陷入了西西弗斯的困境。
新用户的获取越来越贵，一个有效金融用户的获取成本高达数百元、上千元，这钱花着真心疼;做注册刺激，哪怕 10 元的物质刺激都能引起用户的兴趣，那直接想办法做活动，把这 10 元给用户行不行?
答案是，不行。因为信息获取成本的差别，这 10 元中的9块钱都落入了黑产率领的僵尸军团手中。
业内人士表示， 羊毛党的加入不仅使活动的效果大打折扣且大部分补贴都被羊毛党拿走，甚至有的平台甚至直接就被薅羊毛薅到倒闭，
电商业的羊毛党主要是通过黑卡注册账号，利用这些账号进行帮商家刷单、刷信誉等作弊行为，对电商的评价体系造成冲击，损害电商平台、正常经营的商家、买家的利益。涉及的电商平台：淘宝、京东、 1 号店、蘑菇街、唯品会等。
还有一些通过社交平台大量注册小号，用这些小号从事发广告、刷粉、刷阅读量、充当网络水军、传播色情内容、进行网络诈骗等等。被攻击更多的社交平台包括：微信、QQ、新浪微博、映客、快手等等。
随着，O2O行业在国内的发展迅猛，各平台为了争夺用户付出了很大代价。
从 团购网站间的千团大战，到 滴滴和快的之间的 20亿天价补贴大战，再到共享单车领域的红包单车大战，战况之激烈举世罕见。广大用户在这些大战中确实获取到了实惠，但是大部都是落入了手里有大量黑卡的羊毛党口袋里。使这些互联网公司付出巨大代价。
