The key to understanding Paypal is this: Their policies in dealing with their customers are all crafted with the assumption that their customers are out to screw them. It’s not that they don’t want to do business with you, it’s that they don’t trust you. Ever. Under any circumstance. They want your money, but they hate you.
They hate you because in a measurable percentage of their transactions, people are trying to screw them over. As the cliché goes, it’s not paranoia when they really are out to get you.
Except that approaching every transaction with that attitude really is paranoia.
And it gets better from there.
