First of all, I have some seriously viral scripts running on Facebook atm. Similar to these, but using a different method.
This is a Javascript method. Where by they lure the user into pasting Javascript into the browser. Because most browsers block the copying and pasting of Javascript they are getting the user to type the letter J followed by their "arvascript:...". Works well on IE and Chrome. FF won't allow you to use Javascript in the browser all together. By doing this you can act as the user and do what you want as the user.
When my script hits the media tonight or tomorrow, and when the method is useless I will detail all
Oh, and do yourself a favor. Never use CPA LEAD. They are bound by Facebook to inform on earners. I've had a number of friends that got a lawsuit and had to hand over thousands, one friend made $240,000. CPA LEAD don't keep the cash, Facebook does. John is an absolute *** with an arrogant attitude. Sorry, was going off topic there.
Instead, get to know some networks that allow shady traffic and create/buy a content locker. I know a one I use that I can referrer you to, and no, I don't make commissions on your earnings ... I don't need to.
