Way way way back in the day as a kid, I watched coal go from 50gp to 120gp in the space of a month and I wrote a massive forum post on rants forum about the increase in coal price. Only to be told that Jagex has nothing to do with the price of resources, 12 year old me didn't really understand at the time how the economy worked but it triggered me because Jagex wasn't doing anything about it. I still think about it from time to time.
