that is, if I start a new account and I will not break the rules, they will still ban me? why I cannot be on this forum or am I of the wrong nationality
Has nothing to do with the nationality !
Doesn't matter if you are german , spain , english , russian , Maori , or something else !
You broke the rules , and that's the punishment !
If you create a new account , that is not allowed and ban evasion and will be banned again !
