maybe I will start all over again with this new account. Can you tell me a topic that provides steps that beginners must do in order to rank up?
In order to rank up, you'll need to have merits and activity. In summary, you slowly gain activity points for staying active and merits for making useful/helpful posts.
The issue of his banned account must be addressed first, he can not just start using this account now (aside posting in meta about the banned account) once that is resolved, he can then be using this one or the old receovered one depending on the final discussion. If not, this account will only be considered as ban evasion which can result to another ban.
because I really don't know why my account was banned, if I can't go back, it's okay if I start again from scratch
