You have been permanently banned by a forum moderator, probably due to spam or plagiarism.
My guess is you plagiarized something, and I'm also fairly certain someone will show up with the evidence of that.
Wait, what? Did the ban notice change or am I just imagining things? I don't think it used to say anything about plagiarism.

Something has happened, but I don't really want to try it out with my own account, if there's a new ban notice or not
