For anyone that's using VPN's, Disable it before you logon to facebook, They are really cracking down on anyone that uses a VPN due to a lot of scammers using VPN's to bypass certain geo restrictions.
My Facebook account got disabled 2 days ago, I managed to get in touch with customer service, They reinstated it and even without using a VPN they disabled it again only a few hours ago, this time for reasons unknown.
So just be warned.
