Prevent site from getting loaded on iframe

What if somebody loads your obfuscated fancy javascript or AJAX methods to drive traffic to their site utilising your bandwidth? Here is a simple solution in javascript.

<script type="text/javascript">
//<![CDATA[
    if (window.top !== window.self) {
        document.write = "";
        window.top.location = window.self.location;
        setTimeout(function () {
            document.body.innerHTML = '';
        }, 1);
        window.self.onload = function (evt) {
            document.body.innerHTML = '';
        }; 
    }
//]]>
</script>

Paste that javascript snippet inside your head tag of your html.
Twitter(Dustin Diaz) uses that at the Twitter Profile Widget Page. :(
I found it the hard way (lol). Way to go Dustin!
