I didn't complain about people making gold, but ok...
Probably not worth trying to explain to you but here goes. Folks auto post items with that mod at ludicrous prices based on other server averages and non-local data. People start keying their prices off the crazy ones and soon we've got 9/9 helms up for over 1k. I've regularly chatted with sellers about it and they usually agree and complain that their mod did it by itself. That is what I think ruins the economy, not sniping lol. It's when we just normalize all AHs to some server average that they lose their local character and economic differences.
Hopefully that makes sense to you even through the rage you seem to have about the topic.
