Protect your email address placed at a web-page

Bad guys scan the web in looking for email addresses for their spam bases.
Their bot-scripts can detect your email address when you place it at a web-page.

Now what? Do you give the email address to your visitors?
You can protect your address at your web-pages.


In the previous post we used unicode encoding to cloak a Return URL of your order form. The same encoding will help us to protect email address from most of scanning scripts.

The simplest way to detect an email address is to scan a page on the <a href="mailto:..."> signature. So we have to encode this value like below.
<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;...">

Web-browsers understand this encoding and would show this as a regular link to email. And when you place a code like this:

<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#109;&#105;
&#99;&#104;&#101;&#108;&#64;&#105;&#99;&#111;&#100;&#101;&#114;
&#46;&#99;&#111;&#109;
" > &#109;&#105;&#99;&#104;&#101;&#108;
&#64;&#105;&#99;&#111;&#100;&#101;&#114;&#46;&#99;&#111;&#109;

</a>

You’ll get a regular email-link:

 
michel@icoder.com
 

 
Now the form to encode your email.
