"Because we can and it's free"

The common way for a person to play Maple is to either use NX to purchase incentives, or to play FM, exchanging lengthy efforts for mesos, and through MTS, NX. Most I met agree Maple is not farm-friendly, and the vast majority of people I know buy NX. I have met some rare people who are able to play Maple, buy equipment, and pay for pots without expending a lot of money. One method I am aware of is the multi-marriage method, where a person marries his mains and mules (perhaps to each other) and farms apples. Another is to sell hard-to-reach store items, such as summoning rocks, in FM. A third, (mage only and controversial) method is to sell leech.

What are the methods you know, if any, to defeat the spend-till-you-drop system of Maple? How would you farm Maple to avoid feeding Nazison 50k NX per day?
