Trading and game economy ruined by gold farmers

I know its early access, but exactly that should be a fact of addressing the issue with gold farmers / bots who use 3rd party apps to buy of every valuable item on the trading site then raise its price to unimaginable heights.

I am now trying to buy a few unique items for 3 days in a row where all the posters who post it at a price between 1 - 5 ex, never respond, just to post it later at a price of 1 divine or more.. 99% of them are asian 'players', probably employees of a gold farmer who do nothing else than exploit the trading market at our costs.

Not sure how or if there is anything GGG can do, but probably an auction house with some restrictions - rules, could be a solution.
