If there is any company that can "ban your account" which would result in big problems for you (because, for example, they host your E-mail which means you've just lost access to password recovery for every account you have) with no recourse or due process, you should seriously rethink your approach to your online life.

Host your own E-mail, people, or use reliable E-mail providers that are not huge corpo-behemoths that sell you to advertisers. Those smaller E-mail providers will have actual support that you can contact in case of problems and will not "ban you".

Alternatively, impose regulatory requirements to keep the 99% who aren't you safe from big tech companies making decisions for their own convenience.
