You did something wrong. You were punished in your own words. This means you are a CHEATER! You cheated. That is all the proof anyone needs.
Now if you dont think you were punished then I guess you didnt cheat?
Its already been proven. Your case was reviewed and you were handed down a guilty sentence. Since you wanted to be big and bad and point out your own crime when no one was even looking at you as a cheater you must take your medicine.
Now if you were not punished, then clearly state is so.
