They permanently froze my account after I refunded everyone and refused to talk to me when I called. I wasn't able to get a merchant account and I lost thousands of PayPal recurring subscriptions. This was the death of my first start-up.
PayPal is a scam and it's not as uncommon as you think. If you're using PayPal, your time will come. I didn't think they would do it to me either, they never bothered me once until all of this went down.
