Autobahn without consideration of the reason is generally not serious, especially given the fact that no one responds to the letters of appeal. Where is the feedback?

You always see the reason in the ban message.
You have been permanently banned by a forum moderator, probably due to spam or plagiarism.
so there is no need to reply to the appeal emails.
And I have a question.
What harm to the forum carries the copied phrase in the topic with the bounty a year and a half ago?
And what harm would you get if you wrote your own content or at least included a link to the source of information?
Plagiarism is very unethical and it's not encouraged in so many places in our societies. It's an act of arrogance to copy some content and not give credit to the original author. It's like theft.
