## 外掛說明

Anti-Captcha is a transparent spam solution that does not require any end-user interaction.

It is based on a nonce key, which is dynamically inserted using randomly generated(
and obfuscated) javascript.

The aim of this plugin is to prevent automated attacks (by bots) on the following
WordPress actions:

 * Posting comments
 * Registering for a new account
 * Requesting a lost password

When a comment is posted without a valid Anti-Captcha token, it shall be _instantly
marked as spam_. This way, you can always manually approve this comment in hindsight
if it appeared to be sincere.

## 安裝方式

To install simply:

 1. Upload the ‘anti-captcha’ folder to the /wp-content/plugins/ directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress

  Is javascript required by the user?

Yes, however this sounds worse then it is.
 Generally, it’s frowned upon if you 
don’t write javascript in an unobstructive way. The reason for this is that some
visitors don’t support javascript but should still be able to get around your website.

AFAIK there are four types of user-agents not supporting javascript:

 * Search-engine spider bots
 * Users of a command-line browser (like Lynx)
 * Users who actively disabled javascript in their browser
 * Mischievous bots trying to spam or hack into your blog

Obviously, search-engines don’t need to comment, register or login so they can be
ruled out.
 Lynx users and users with javascript disabled are likely to be a _very
small_ percentage of the internet population, who have actively excluded themselves
from certain webfeatures. Finally, badly behaving bots, is what the Anti-Captcha
plugin is trying to block.

This plugin does not work in recent WordPress versions. It filters out every comment
as spam, also those by humans, not bots.
