I was in the process of selling a book to them and was asked what method of payment I'd like, Paypal or check. I chose Paypal. I thought it odd that I would have to log into Paypal, not just provide my email. I did log-in then they asked for authorization to access my account information, like my birthdate, contacts, phone numbers, etc. At that point I canceled the transaction and logged into PayPal and changed my password. I think they are a fraudulent outfit.
