I see this often, after I click someones affiliate link in an email or on a webpage, the destination site loads as a blank white page, with this statement only:

Unauthorized URL Modification


It happens to me several times every week. While I don't buy everything thrown at me, it makes me wonder how many sales marketers are losing because I see this a lot.

What did they do to create this message, so that when I make affiliate links it doesn't happen to me?

Thank you.
