What's worse is that when they ban you they refuse to talk to you. No explanation, no justification, no appeal. Just an automated reply to look at their ToS and you can never hold a coinbase account again.
I agree that it's a frustrating / bad experience for customers especially when they get flagged by a false alarm e.g. https://news.bitcoin.com/the-moss-piglet-dilemma-paypal-bans...
