Facebook account disabled, why?

Hello, my farmville account has been disabiled and I don't know why? I was taking care of my husbands farm and my sons farm so i was switching back and forth. I don't know if this is why or not. Is there anyway i can get my facebook account back and my farm also? I have a lot of family members on and have quite a bit of money invested in my farm, can anyone help?

Thanks
