What if it goes like this "You have been permanently banned by a forum moderator, probably due to spam or plagiarism. You may appeal here, but your chances are not good" Is there a chance for this? I've read some quotes and allegations about this topic and in my concern that most of this kind of a problem has not yet solved or not given a chance just once, is it easy to be banned without any warnings?
Then, as the message says, it's permanent. There is no warning because you should have read the rules and learned that plagiarizing is not allowed. Btw, plagiarism is illegal/unethical/not cool in every single country in the world. It's not like you should be warned that you shouldn't do it.
