Not trying to poke the bear with a stick or anything.....(well maybe I am )
It's obvious someone with 500+ market trades is buying their resources. However I'm not really sure what the problem is with that. When the farmers are pulling in 1m+ a day they wont be able to buy that every day unless they're really rich! In which case we should thank those people for paying to keep this game we love alive!
I honestly think the farmers will win over the pp spenders, when the markets are dry the farmers are still farming. You can always spot the farmers in the end world rankings because they're all in the top ranks. It's impossible to remain at the top without farming hard ALL world.
