I bought an account from the owner. Not hacked one
Moderators bans a man who violated the rules and its forbidden to create a new account on the forum for him. I got a ban for something I didn't do and now I cant write on the forum
Probably the original owner already know that he is being reported for plagiarism and the account is on the risk of getting banned, and then he sold his account to you which is the best thing happened in the original owner's side, but unfortunately it is the worst thing happened to your side. You got scammed.
You will not get your account unbanned, even if you have all the valid data in your hand.
