I answered a person a question and made a mistake in quoting. Look at the meaning of the topic and my response to the post of man.
Am I really stupid enough to post copied text almost immediately?
So we can assume that you already know the forum rules that plagiarism is prohibited and could lead you to ban? If it's that so, then why haven't examine your post at the beginning if it has an error or not before just leaving it because you've answer what you've said so. You can appeal on your ban and let a global mod or admin decide upon your case.
