Proxy problem on Fb - Need Help

I have recently bought couple of private proxies for massplanner use for fb accs. The thing is that whenever I try to log in using a new proxy it fails. Then when I try to log in from my regular IP fb gives me an alert that someone from not regular location tried to log in. While the its perfectly understandable that when fb sees a brand new ip form another country that tries to log in it stops it, but how can I deal with it? Anyone?

anubody?
