The key word here is "again". So you're admitting that it was actually your account that was banned, not your brother's?
Read the quoted message too. He blaming that you registered account in 2021. I opened up it again in 2022. It means I login again in 2022.
I am sorry to disappoint you, but it does not work that way. You have to demonstrate that your account was beneficial to the community and that you had positive contributions. I do not see that from your history.
My post history is full of political debate. In my Local Board.
But I think I should never lose my hope.
