Maybe they have changed (we still use PayPal and haven't had anymore issues), but on Thanksgiving day a few years ago, they completely shut us off with no warning. At least Stripe gave a week. They also said all of our funds (which at the time was most of our cash...not making that mistake again) would be held for 6 months. We lost a week of revenue before getting reinstated after I finally got connected with a VP that got it sorted out.
