I don't care if you are a bootstrap startup or a multi-million dollar vc funded giant, I will signup to your service with an email alias. This is the reason why. It's easy to block the account if spammers get hold of it, nobody is able to double check if I use other services by comparing login emails, I know which service has leaked my email... bottom line, I am in control. I feel sorry for these Coinbase users.
