<p>One of the most common ways that spammers get e-mail addresses is through webpage harvesting.
They crawl thousands of pages looking for e-mail addresses; if they find one in the form of myuser@mydomain.com
they'll add you to their databases. For more info read this
<a href="http://www.cdt.org/speech/spam/030319spamreport.shtml">interesting study</a>.</p>
<p>enmDespamify will help you "hide" your addresses by translating them into HTML character entities (for
example 'a'=&#097; 'b'=&#098; etc).</p>
<p>Just type in your e-mail address, click encode, and the replace every occurence of your address in your webpages with
the encoded version. Your browser will render it as a normal looking e-mail address but it is MUCH harder for them
to extract while crawling your site.</p>
<p>Good luck...</p>
