I sell custom items which require specific information from the customer in order for me to provide the product. I have a "customer" who appears to be mentally challenged. He enters orders but will not provide the information needed. Each time this happens, I have to refund his money (which costs me a small paypal surcharge) and, since the order comes in through ebay, I have to deal with their rules as well. I wish to block this person from making purchases. Is there a way to do that?
