I did it like everyone said. I arleady had massplanner, I bought 5 proxies all with locations in the USA, cleared cookies and history before making every mail account and facebook account. All good. I put them into massplanner and in 2 minutes they began to drop, facebook asking for ID. One odd thing that I saw was that, when I was completing the facebook profile with photos and hometown, the suggested hometown was my own, like facebook knew where I was connecting from. How can they still know after implementing the proxy? Maybe some advices? Thank you!
