解决恶意注册的方法

我的博客刚建立没多久文章也没多少原创，大部分都是转载的，可是虽然这样但是为什么还有人会去恶意注册我的博客呢？（理解不了，誰知道原因可以告诉我吗？那些恶意注册的人，有什么企图或者用处？）

为了解决恶意注册的问题我找了很多办法，用了很多插件，最后还是选择了HumanCaptcha by Outerbridge(感觉很好玩,但是就算你使用了这个插件，问题设置的不够多还是会有机器人批量注册)

官方简介如下（全站支持划词翻译可以试一下）：

Most captchas are based on the requirement to reproduce a number of randomly-generated characters (which are sometimes blurred, jiggled and/or on a fuzzy background). HumanCaptcha generates a simple question which the user must answer using logical thought. HumanCaptcha is much more accessible than standard captchas, which many people find difficult to read or understand. Visually impaired people are more likely to be able to use HumanCaptcha than a character-based one.

CAPTCHAs are useful for improving security in a number of situations, for example:

Reducing Comment Spam in Blogs Most bloggers will have come across programs that submit spam comments, often with the aim of improving the search engine ranking of a website. By using a CAPTCHA, only humans can enter comments on your blog, and people do not need to sign up before they enter a comment.

Protecting Email Addresses From Scrapers Spammers crawl the web looking for e-mail addresses rendered in text. CAPTCHAs can hide your e-mail address from web scrapers, by requiring users to solve a CAPTCHA before revealing your e-mail.

Deterring Viruses, Worms and Spam CAPTCHAs may reduce the likelihood of e-mailed viruses, worms and spam, by only accepting an e-mail if it has been established that there is a human behind the sending computer.

基于需求大多数验证码复制大量的随机生成字符(有时模糊,摧和/或模糊背景)。HumanCaptcha生成一个简单的问题,用户使用逻辑思维必须回答。HumanCaptcha比标准更容易获得验证码,许多人发现难于阅读和理解的问题。视力受损的人更有可能能够使用HumanCaptcha比基于字符。
提高安全验证码是有用的在许多情况下,例如:
减少垃圾评论博客大多数博客会遇到程序提交垃圾评论,通常目标是提高一个网站的搜索引擎排名。通过使用一个验证码,只有人类可以输入博客上的评论,人们不需要注册之前输入的评论。
保护从刮刀垃圾邮件发送者电子邮件地址抓取网页寻找电子邮件地址中呈现文本。验证码可以从web scraper隐藏您的电子邮件地址,要求用户在暴露你的电子邮件之前解决一个验证码。
阻止病毒、蠕虫和垃圾邮件验证码可能会减少电子邮件病毒的可能性,蠕虫和垃圾邮件,只接受电子邮件如果它已经建立,后面有一个人发送计算机。

使用后效果图如下：

后台设置界面如下（自己简单的翻译了一下，有需要的可以留言我把翻译<不是汉化>过的链接发给他）：
