The problem with staffs enforcing action is that it becomes quickly borderline of "for profit" and "for scam", a person who sells sand bags at 15% higher margin at west argent gate, or a person who sells hexathlon items by the greg at twice the price, and a person who sells BD torso for 1.5B.
Now, does that mean they are scam? Not necessarily, and you have something like BD torso that's really unpriceable, so as soon you traded you'll run and come up "but dad! I paid too much for this!"
We are not intervene the game itself, it's mere the economy that which you must become familiar with.
