How to fuck with iframe traffic trade cheaters

I was a bit suspicious when this Alexa 200k site was sending the highest # of referred visitors, even more than much bigger sites.

Finally I viewed source and found this:

I'm actually kinda glad I discovered it though, b/c then I was able to add an iframe-buster.

<SCRIPT language="JavaScript" TYPE="text/JavaScript">
function handleError() {
// window.parent.location='http://goatse.ragingfist.net/';
window.parent.location='http://some-url.com/';
}

window.onerror = handleError;
if (window.parent.frames.length>0) {
if (window.parent.document.body.innerHTML) {
//do nothing
}
}
</SCRIPT>

Damn - he's already figured it out even before I could post this.

For a few there, all of his traffic was getting redirected.
