Hi there!
I recently wrote a FB exploit that allows you to turn your each one of website's visitors into a facebook like for your page(s)! This will happen automatically, and without the visitor knowing. The only requirement, is that they are currently logged into facebook at the time. I can provide full demonstration, and show you websites that I have installed it upon. Currently, my newest page has reached ~2,450 likes in only a few days of use :)
Ready to deliver ASAP - with ability to customize it to your needs!
