The problem occured in the US; perhaps not in other countries. When PayPal says you need to attach a Credit Card to your account (I forget the circumstances under which you need to do that; it's not required to be Verified but I do know it used to be required to get a PayPal Debit Card; perhaps not anymore, as it's been years since I've had my PayPal Debit Card) and you instead attach a Debit Card, they could close an account.
The reason I know this is that years ago I paid someone (an Australian national living in the US) using PayPal, and he had his account suspended for supplying a Debit Card instead when they asked him for a Credit Card.
PayPal acts differently in different countries.
Best is probably to check with PayPal support if unclear, when they ask for a Credit Card.
