Spammed Out?  - or

Prevent Spam Email Crawlers from Harvesting Your Site

category: spamming, javascript

I don't know about you, but my delete key is wearing out. If you have your email address displayed on a web page, then here is some javascript that will help you slow the spammers down a little. What it does is create your email link when your page loads, providing no email address for spam crawlers to harvest. I don't know how smart these crawlers have become, so I have used silly variable names, an "%40" instead of the typical "@" sign, and spread the relevant components around a little. This may be a little paranoid, but as I said, my delete key...

This part goes in the head of your document:

<script language="Javascript">
<!--
// these two variables are used in the email address creation, put
// them in the head of your document with your other javascript.
//

last = "yourdomain.com";
badword = "'mailto:";
//-->
</script>


This part goes in place of your email link:

<p class="links">
<script language="Javascript">
<!--
// Put this code in the body of your page in place of you email link,
// and style it however you like. "doodaa" is your email address to
// the left of the @ sign. "Email Myname" is what appears on your page.
doodaa = "myname";
document.write("<a href=" + badword + doodaa + "%40"
+ last + "'>");
document.write("Email Myname");
document.write("</a>");
//-->
</script>
</p>

Good Luck.
