Pulling Proxies

I know that the elite anonymous proxies are the only undetectable proxies to use, but im trying to use many facebook accounts, and im just not finding enough Elite Anonymous (maybe 200) when using a program to find proxies, are there any other type of proxies that I could get away with using for facebook? I actually had about 50 of my accounts deleted by facebook, im not sure if its because of IP, or because they noticed that they are being used for voting purposes only...
