I don't understand your predicament. Can you provide more details? You say you can't log in with Facebook but from my experience I've never needed to log in. When I open the app it takes me straight into the game. My account is linked to Facebook to retrieve my save data if I change devices, but I don't need to log in to play the game, and I can unlink my Facebook account at any time and still play the game. Regardless, you shouldn't try to log in anyway until the House Pride event has finished on the 7th. Even if you haven't been banned, you will be if you try to log in while the pvp event is happening.
