Not really profitable at all, but something that a script can focus on maintenance of the antiban and making less detected than making the method better seeing how the method is all that you can do. It's a way for you to thieve without having to worrying about the bot dying, and for you to make some money without banking or needing to reset on food.
Breakdown of money /hr
Nature runes: 259~ + Coins: 777 = 70k~ 1.5/hrs.
70k x 2 = 140k/3hrs
140k / 3 = ~45k/hr, while in mind not having to deal with deathwalking or food and still making profit. So am happy that someone made a script for this, as my autohotkey one has helped me a bunch when I need to leave for a couple of hours.
