## 説明

This plugin provides an unobtrusive yet efficient protection against email harvesters/
spambots. Here is a [demo](https://pixeline.be/blog/email-protector-demo-4258.html).

Post/page authors may write email addresses in their article in the usual format(“
john@doe.com”) without exposing them to spam email harvesters. The plugin takes 
care of the obfuscation, implementing a graceful degradation technique focusing 
on usability so as to protect your email addresses from harvesters while keeping
them usable to your human visitors.

The plugin replaces any email address found in posts, pages, comments and excerpts,
and replace them by a bit of html markup that should deceive most email harvesters:`
<span class="email">john(replace the parenthesis by @)doe.com</span>`.
 If javascript
is available, it will display a clickable link and display the original email to
the human user. Maximum usability, maximum protection.

**Please [rate the plugin](https://wordpress.org/extend/plugins/pixelines-email-protector/)
if you like it.**

### 使用法

Write your email addresses inside your posts and pages as usual. When the plugin
is activated, it will replace them by a human-readable html string that explains
how to deduce the email address, and if javascript is available (99.9% of the time),
the original email address will be displayed as a clickable mailto: link. For example:

Hello john@doe.com. How are you today? will become John( replace these parenthesis
by @ )doe.com.

Additionally, you can specify what the mailto: link should look like by sticking
a parenthesis inside of which you put the visible link text, like this:

    ```
    Hello john@doe.com(John Doe). How are you today?
    ```

will become
 John( replace these parenthesis by @ )doe.com.

#### inside a theme

If you need to protect emails inside your Theme’s files (like the footer.php for
example), you can use the function safe_email() like this:

    ```
     echo safe_email('you@domain.com'); <h3>Contribute</h3>
    ```

## インストール

 1. Unzip the file into your wp-content/plugins directory.
 2. In your wp-admin screen, activate the plugin. That’s it, your emails are now safe!

Additionally, there is a Settings screen (Email Protector) allowing you you to customize
the text that is displayed as a replacement to the email address.

I was looking for an alternative, more up-to-date plugin. All the others haven’t
released any updates for quite some time. Now I have an up-to-date plugin to protect
my emails again. It works as described and expected.

Thanks for creating this plugin! It works great. There are a couple of features,
however, that I think should be added. Otherwise, bots will soon learn how to parse
the emails you’re protecting. 1. The class name should be customizable on the settings
page. 2. The parenthesis should be included in the text that the admin is able to
customize. Without these 2 changes, it’s very easy to write a regex that extracts
emails.

This plugin ended up working great for me. Initially I had already coded the mailto
links. I had used the email address as the text to link to, so that was a problem.
I was able to resolve that my removing the mailto link and keeping only the email
address and that worked perfectly. Now all email addresses added to the site will
be protected. thank you!

I maintain a web site that has addresses of an organization’s board members. Wanting
to better protect them from spam, I tried this plugin and am quite pleased. On the
WordPress “Edit Page” for the page in question I enter email addresses in the form
myname@myorg.com([Click here to send])* The plugin takes everything in the parentheses
and displays that as the link. I’ve told the board members that if they’d prefer,
I can do something like myname [at] myorg [dot] com or any variation they’d prefer,
for their email address. At the bottom of the page in question I added the text *
This site uses an “anonymizer” to protect email addresses from spammers. Click on
the text if you want to send someone an email. In many browsers, moving the pointer
to the link will give you a popup that displays the actual email address (preceded
by “mailto:”).

The Email Protector plugin is useful but needs amending – domain extensions can 
now exceed 4 characters in length. e.g. .london
