There are a variety of ways to protect and hide emails and other information from email harvesters or just to protect your privacy through obfuscation, a technique on the web that allows displaying of email and content within web browsers so browsers can understand them, but masks them from web crawlers and bots.
A typical email link would be:
<a href="mailto:email@example.com" title="Email Fred">email</a>
An obfuscated email address link would look like this:
<a href="mailto:&#102;&#114;&#101;&#100;&#115;&#109;&#105;&#116;&#104;&#064;&#103;&#109;&#097;&#105;&#108;&#046;&#099;&#111;&#109;" title="Email Fred">email</a>
