Creating a new account and reforming.

I was perma'd for toxicity. I need to know if riot would ban a new account a made if they were able to figure out it was me because I don't want to spend money on an account to have some of my favorite skins back just so riot can ban it even if my behavior has improved. I have seen people say you can spend rp on a new account after ban, but the terms of use says riot can ban any accounts you make after you have one terminated. Does anyone know if riot follows this rule strictly if at all?
