Facebook Auto Like Script / Code

I need a script which likes a website automatically without any user interaction. 1. No application 2. No click on Like button / no click on website (user will just visit the website and without his click the FB Like should happen) 3. Like will happen once website page is loaded (I mean website is visited by any user who is already logged into Facebook) 4. if user is not already logged into Facebook, no pop up window will open. 5. for every like a post will go to user's profile wall in Facebook 6. Script should work with XFBML, not iframe! Important: 1. You must show me live and working demo! No demo = no payment! 2. NO ADVANCE PAYMENT, SO NO REQUEST PLEASE 3. If you have demo please show me in PM quick! Please ONLY PM me if you can show me auto like live. No payment before watching it live.
