PayPal doesn't put a merchant through the usual rigorous application that a bank or other merchant account provider does. The price for this easy entry into online payments, however, is that PayPal can potentially freeze your account due to a sudden spike in sales volumes or other security triggers. And if your business deals in any adult toys or erotic literature, you may not want to adopt PayPal as your merchant account provider due to its recent ban on adult products.
