Looking for someone to write me a full-proof referrer spoofing/faking code in php. What i want to do is : i will send traffic to this "spoof.php" and i want this "spoof.php" to redirect users to "x-site" with referral link of my choice. Budget : $10 USD
No, you cannot. You cannot make referrer as google or facebook or youtube or any other site which you don't own.
Ofcourse it can... take a look at your own stats - you'll find plenty of spoofed referral info in there. Its an old school trick from when people used to publish lists of their "top referrers". While I doubt anyone gives those lists anymore the spoofed traffic continues.
