"You have been permanently banned by a forum moderator, probably due to spam or plagiarism"
You have been permanently banned because you go against the rules, when you did something wrong just face it, spam or plagiarism should not be tolerated so you're facing the consequences now. to recover you're banned account you need to talk to the Mod respectfully for they are the only one can get you back you're account going against them will only make your comeback in jeopardy.
