To clarify, since someone raised huge concern about being "banned" due to having multiple facebook account:
First of all I do not operate or control facebook (and it's accounts) and that means it's up to them decide what to do when you have multiple facebook account (hint they don't allow it) but anyhow, I do not chase down people who use multiple facebook accounts, but neither do I help out people who "accidently" lose their facebook accounts due to any reason.
It is cornerstone that people use their primary and legitimate facebook account because facebook doesn't ban or suspend accounts for no reason and they wouldn't impede your account, and as long your facebook account is in good standing, you can always then authorize yourself to login PKO.
