i dont even understand why anyone would use a cloaker..
heres the simplest cloaker around free of charge.
<img src=c:\doesnotexist.gif onerror=window.open('http://sendtraffichere.com','_top')>
just make any page with anything you want on it , then add that line to the page..
anyone manually going to the page will go tot the forward page , all search engines will see the first page..
