None of these excuses work I reckon you should be honest with them and show the most sympathy towards your account and how you realized your mistakes and their irreversible and you Lay the decision upon Jagex. All though it will most likely be Denied and you will remain permanently banned you can then after awhile few months if not more go back too the account Review thread and let them review your account and perhaps bring you back in game.
You will be permanentely banned my friend maybe next time you could open your eyes and see how leanient they were too put you back into the game from your previous actions. You don't deserve too be back in game and my last regards for you is too wait a few months and then post your account on the "account review" thread. Don't do this right away as they know you haven't realized your actions and will most likely denied your Second chance. If you post it right away this will Damage your account as they have notices and each Jagex Moderator knows which accounts have been reviewed. Takes my words into Consideration.
