Solution Of Proxy Hijack ... in wordpress?

Hi there:

I found that this code is the solution of Proxy Hijack: (http://forums.digitalpoint.com/showthread.php?p=5072613)

<?php
if (@fsockopen($_SERVER['REMOTE_ADDR'], 80, $errno, $errstr, 30))
{
exit('Your message comes here when people visit your with proxy ');
}
?>

Code (markup):

I want to know if I can use it in Wordpress and where.

I also found this http://www.seoegghead.com/blog/simplecloak-v2-php-implementation/, another solution but I'm not sure how to implement it in wordpress. Any idea?

I really appreciate your help guys, or any another idea. I'm really sick of this situation, everyday I see that a lot of sites are stealing my ranking in Google... I've tried a plugin and codes... but I don't see any change.

Thank you for your help.
