My preferred money making bot (p2p) would be RiDiverse. It can do a wide variety of tasks, so it is possible to make a wide range of gp/hour.
Some of the most common methods with RiDiverse are:
Unfinished Potion making with Scroll of Cleansing (300-1000k an hour usually)
Superglass Make with Mousekeys and Full Bank (200-900k an hour)
Mahogany Plank Make with Lunars (usually profitable, but ranges between 100-500k an hour)
Superheating certain bars (steel is most common, mithril or addy may be profitable as well) (~150-300k an hour *I think*)
Bolt tipping diamond/ruby bolts (profits range from 200-800k an hour depending on the market)
The above methods will vastly increase their profitability once the Anti-Botting update is released with Botany Bay. (Yes RiDiverse will still work and will still be safe to use after the update)
