A copy paste plagiarism caused ban is not reversed. This is clearly explained in the forum rules. If you are not willing to read the before you start posting in the forum then nobody can help you. Plagiarism is a serious offence and your ban will not be lifted under any circumstances. You are allowed to make posts in "Meta" about your ban but you are not getting your account back. Even if you under the rules now and feel sorry you will have to bear the punishment.
