Hi , as @
Chillivanilli mentionned the method is old, I guess it works now for some hours per day, you are still able to spoof ref and fake the ref using this method , but I guess Google is planning to fix this bug after two years (you're too late in the forum unfortunately) . Still I will try to look it up for you, can you please send me the link you have generated on private message and I will check it for you , also include in the message your website and your keyword , and welcome to the AngeClub :D
