I made a mistake on the old account and realized it, why prohibit a new one if I realized the mistake and do not break more
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.
was banned go fuck from the forum? why they didn't tell me right away? I tried to develop and did not make more mistakes
The reply above implies that you follow due process in order to get your account back or reasons why it was Ban thereby continue with a new phase in the forum.
why delete my posts? it turns out I'm right
No!! it doesn't just because of your Ban evasion.
Hope you understand the rules and be guided by them strictly. Suggestions have be given that you open a thread on meta to ask what leads to your account be Banned.
