Sign up is pretty automatic but verification of ID etc is not. The issue is as soon as they start to get swamped, things slow down and people submit more tickets, making the situation worse. I have had issues with other exchanges. I’m still waiting for a withdrawal I made on 30 Dec 17 on one exchange and on another, they suspected hacking so locked the account down (good) but then haven’t responded to tickets for two weeks and won’t allow trading again at present (bad).
