> If people don't trust us with their email address, I don't think it's fair for them to expect us to trust them with an account on our service if they provide a fake email address.

I've not used a single website that hasn't flooded me with "email newsletters", "promotions" and "reminders". Even my damn utility companies (each on their unique addresses) both sold and spammed the address I gave them with the stuff.

There is no trust.
