Steps 1 - 6:
1) Wait for a full moon - J mods tend to ban less on those days
2) Close the blinds on any windows in your entire house, Jagex has eyes everywhere - YOU CAN NEVER BE TO SAFE
3) Light 2 candles - One on each side of your monitor with a piece of garlic in between (YOU MUST PLACE THE GARLIC EXACTLY 3 INCHES AWAY FROM EACH CANDLE OR THIS WILL NOT WORK)
4) Tear an extremely small piece of garlic and place it in the melted wax of your now lit candles - This will deter any spirits hired by Jagex from catching you in the act.
5) Open Runescape client *MUST OPEN CLIENT WITH PINKY TOE*
6) Trade gold over
