Did you plagiarise?
If you did plagiarised and with such negative trust (bad net effects), I don't think you can get reduced sentence from your permanent ban.
No I did not plagiarize anywhere. If there is any proof let them prove it and do it.
Else they could have allocate one moderators to create one thread to keep on update with the user info and proof of banning.
If it is saying due to spam and plagiarism then how come it's unknown reason :-)
Anyway, if you are really sure about that you have not done any plagiarism or never done any spam then we my expect an explanation from Mod or whoever banned the account.
Sorry to hear the situation.
I guess you mean apply for unban?
I understand this has happened to many people, but if they ban without any proof and just clicking the ban button for one account does not seem fair.
If there is no reason, they need to correct things else if they can prove that I have plagiarized somewhere. I could lock this thread and move away.
