I think we all knew this will happen. I am not saying this for my own part, but for you guys that still try to discover it. The trick is officially patched. I can only do 100K daily now with my old trick (the referrers are Facebook and Twitter - or any referrer you want really, even if the domain doesn't exist) For those who are still trying to figure it out: give up. I will reveal the method in a week or so anyways. It's dead.
