You already admitted to copying it. You said you got it from a friend and posted it here. That, is copying. Whether or not you directly took it from that site does not matter. The fact is, either way you copied it without at least noting that you did not create it. There is more evidence against you that it existed on that site before you ever posted it here, as well as countless eye witness accounts against you. It is time to resign, because all you are doing at this point is hiding behind your powers.
You admitted to copying the article. Lemme say that a third time; you admitted to copying the article.
" if you can get any concrete proof that I did actually copy this article, I'll quit this site forever."
Good bye?
