Hello, I am testing three days the likejacking with the new Confirm problem that Facebook puts. When i put the script in a new domain and boost it a little, after a few minutes Facebook put the Confirm button. I tested in 5 different domains and after that i put the like button visible as usual to a new domain again. Again, after some minutes i get blocked my the "Confirm" button. I cant understand exactly what facebook tracks and block my domains. Maybe my server's IP or the pages which i boost the website.. Has anyone know something more specific?
