I signed up with a throw-away / temp email address and my account got disabled.
You are not allowed to use throwaway email addresses.
It is important, that we are able to reach you when we need to.
You are also doing exactly what you are trying to avoid.
You give your email address deliberately and voluntarily to shady people who collect real email addresses this way to sell them to spammers and scammers.
Or did you really think that they spend thousands of dollars creating and maintaining that service every month just so they can do a favor to you for free?
