You read all the rules after the fact, and apparently you haven't read any of the other ban appeal threads in Meta that say almost exactly what you said in this one.  If you had, you'd know that pleading for forgiveness/begging/pleading doesn't work and that your account won't be unbanned. 

If you acknowledge your rule-breaking and that you "deserve all punishment", then you're going to have to accept what I just stated above.  People don't get second chances for plagiarism here.  If mods started doing that, they'd be doing it for everyone and the problem would only get worse.  Please don't keep asking for a second chance or forgiveness, because we've heard it all before and it's a waste of your time.
