ok, there is a lot to unpack here.
you are not being unbaned. one reason is, that it is impossible to understand 100% what you are saying. you are writing in english, but its impossible to get what you want to say. even worse than that, you are contradicting yourself multiple times. that also happens in one sentance, if you would have used perdiods to begin with. that makes it even harder to guess what you may wanna say. if i cant understand you, or, you are unwilling/ unable to form proper sentances to make it possible for others to understand you, i am not chancing it. but lets assume i would have unbaned you and you do something against the rules, you can say you havent told us before, that you wouldnt do it. you are even talking a lot about that >>you<< will get another chance and so on, but i thought its about your brother ?? that doesnt make sense, except you are just telling us a story. Why shall it be unfair to doubt people i dont know? i would be an idiot if i would believe every story anyone came up with. Other than that, we have more than enough examples were we being lied at, or they did again what they had done before.
i have never seen anyone writing that way you do and expect others to fully understand you.
the other reason, all the stuff that happened ingame were over a pretty long time. you completly did it on purpose. you created other nicknames in order to insult the staff. that wasnt an error, or a one time mistake. you did this several times. that in itself isnt tolerable and you are the only one to blame here, because you did this to yourself, not we.
