@AC, if you are out there and still reading this.
Most of the sites I know of that index links to sites such as Rapidshare, use HTML magic to forward you to the link without a referrer anyway
I am relatively proficient when it comes to many things web/html related, yet I have never heard of being able to create a link that doesn't pass referrer information. After googling this topic for a little bit, all I see is that most modern browsers now pass the referrer info, even with target="_blank" or when the link is handled via javascript.
That said, I am well aware that "The more I learn, the less I know."... So... Can you enlighten us on this HTML magic to which you refer?
