My wife used our US debit card to order points for a game she was playing on FaceBook & a few weeks later our bank account started showing unauthorized debits that resulted in having to get the card replaced. As this was the only place we used the card it was obviously a FB problem.
We were lucky that the bank refunded all the charges but as I live outside the USA it was a huge hassle.
I have no faith in FB's ability to guard their accounts. I immediately deleted all card information from our FB accounts & will never trust them again.
