You're permanently banned considering Jagex's recent announcement..
"These days we are taking a zero-tolerance approach to macroing. Players caught for macroing don’t receive a warning, or a chance to appeal, or even a last-chance appeal - they are just permanently banned. Don’t make the mistake of believing that we’ll be soft, and that you can get away with it until you are warned. You can’t. Don’t risk your account. By the time you realize you’ve been caught it will be far too late."
See this thread for more info about it: "11th June 2009 - Macro-detection systems update" - Fear not!
