There is no possible way of being unbanned if you found guilty for botting.
They used to just wipe your stats and give like 24 hour bans, but now JaGeX don't fuck around. If you're banned for botting, say goodbye to that accout lol.
It's not unheard of for players to have their accounts unbanned after speaking directly with jmods at runefest - assuming you don't want to go to that extent then you should probably forget about it.
