I tried to pay with paypal from bank account today. However, it shows "This payment can only be funded with eCheck or credit card".

In the "learn more" window it shows " We review every transaction before it is approved, and we may block a payment when we detect a potential risk. Our reviews take into account every aspect of a transaction, including looking at both parties. These decisions help us maintain the integrity of our payments network in the same way as other payment processors: by declining transactions with an unacceptable level of risk. While our fraud measures occasionally block a legitimate payment, to maintain overall security, we cannot overturn any decisions about an individual transaction."

So, does it mean that paypal thinks this transaction is not safe. Should I continue with it or else? Thank you all very much.
