Same punishment as ban evading any ban, self-ban or not. So don't do that. It will make your self-ban a lot longer.
"If you evade a self-ban, all of your new accounts will be banned for the length originally requested and the ban duration is reset on the originally requested accounts." https://royals.ms/forum/threads/so-you-want-a-self-ban-read-here-first.131445/
