The GP fluctuation is mostly due to the recession we're in. People are finding more, and more ways to make money, and Runescape is actually playing a significant part in supplying people that are in crisis due to the economy, and the state It's in. Bots don't bring money into the game, they just disperse more of individual items bought by players, to players and affect the price fluctuation on items, they don't sell to the general store/alch and bring more currency into the game. The GP prices are falling due to the amount of people competing for prices, not due to all the allegations made against botters, the botters are small fries compared to the bulk sellers.
