If Noiz got banned on an alt then got on his main and got his main permabanned for the reason that his alt that is banned is now his main, why is he being banned every time he logs on when the ban for mass RDM is already done on his "main". He's not removed from community.
It makes less sense than if someone got banned for mass rdm got on an alt and that alt gets permanently banned then you permanently ban all his other accounts even after the main's ban is done.
