Why can I only sometimes pay by Paypal?

Due to a change in Paypal's Terms, Gumroad can now only accept payment via paypal only if the VA links a paypal account. Unfortunatly, because of the nature of the stories we write, accepting payments via paypal carries a large risk of the VA's paypal's being shut down, so many don't link these accounts together. Appolagies for any inconvenience caused.
