<p>This plugin adds lines to the virtual robots.txt file (that WordPress creates automagically if the file is not present physically on the server) to block the archive.org bots.</p>
<blockquote>
<p>Please be aware of what this plugin does exactly: If you activate the plugin it will add some lines to the robots.txt file to tell the <a href="https://archive.org/" rel="nofollow ugc">Archive.org bots</a> <strong>not to crawl and index</strong> your page. This means that they won’t store a backup of your site and you won’t be able to browse the different versions of the website through time.</p>
<p>Please keep in mind that if you activate this plugin and your site is deleted from the archive.org index, you can’t undo this. If you remove the plugin and the block of the archive.org bot, they’ll start again crawling and indexing the website from that moment, but all the older information is lost. <strong>Be carefull and think if this is what you want to do!</strong>. If you mess it nobody will not be able to help you (neither we or archive.org).</p>

<p><strong>Please only activate this plugin if you know what you’re doing</strong>.</p>

<p>PHPEnkoder is a port of the excellent <a href="http://hivelogic.com/enkoder" rel="nofollow ugc">Hivelogic<br />
Enkoder</a> to PHP and, more specifically,<br />
to WordPress. It is used to display text in a way that users can see<br />
and bots can’t.</p>
<p>The encoding system is directly and unabashedly stolen from the<br />
BSD-licensed source of Hivelogic Enkoder, which works by randomly<br />
encoding a piece of text and sending to the browser self-evaluating<br />
Javascript that will generate the original text. This works in two<br />
ways: first, a bot must first have a fairly complete Javascript<br />
implementation (in particular, it must have <code>eval</code>); second, the<br />
decoding process can be made arbitrarily computationally<br />
intensive. This is similar to the idea of charging computational<br />
payments to send e-mail, only this is actually implemented.</p>
<p>By default, PHPEnkoder scrambles e-mails in plaintext and in <code>mailto:</code><br />
links.  It additionally provides a shortcode for manual scrambling,<br />
used like so: <code>[enkode text="shown to non-JS browsers"]this will be<br />
scrambled[/enkode]</code>.</p>


PHPEnkoder

Encodes mailto: links and e-mail addresses with JavaScript to stifle webcrawlers.  Automatically turns plaintext e-mails into (enkoded) links.
