And not posible to unban?i dont know that is broke the rules....very bad....
Ignorantia juris non excusat. Sorry, but not knowing the rules isn't an excuse.
Also, plagiarism is not only a crime in many countries, but doing so would result in you being expelled from any university. You should have common sense.
P.S: Keep in mind that you (as a person) got banned. You can't create a new account to keep posting and/or joining bounties or you will be banned again. Actually, you already broke another rule by posting outside your appeal thread (this one), so this account should be banned as well. Even after getting banned, you didn't even try to read the rules. So, how would you deserve a second chance? Very bad...
