I think this back and forth has gone on long enough.
As mentioned before, the Auction House is considered a free market where players may price their wares how they like. This includes putting up items for a low bid but a very high buyout.
It also allows players to remove an auction from the AH if they wish (that is what the deposit fee is for). That is not considered a violation and most especially not Zone/Area Disruption. Sorry. Our Support staff generally will not comment on the validity of a report, only that it will be reviewed and appropriate actions taken based on our policies.
That isn’t to say that policy and functionality cannot change. If you are looking to see a change to how the Auction House functions, can be organized, etc… you’ll want to submit feedback to that effect.
