The Undermine Journal has started dedicating resources to embed reporters in the The Veiled Stair of Pandaria to keep you informed about what's available at the Black Market Auction House.
These reporters do not use the same methods as our sources in the Alliance, Horde, and Neutral auction houses, so, due to their remote location, our communications with them are intermittent. We strive for hourly updates, which is the same frequency we get with other auction houses.
To get this data, we need a character to log in to World of Warcraft and talk to Madam Goya once each hour.
We have all US PvE (RP and Normal) realms covered. We're trying a few PvP realms, but due to the nature of PvP, our characters that survey the auction house are getting killed. So, if you see a level 1 female Dwarf suddenly appear, don't be alarmed, she doesn't have any gold and doesn't want any trouble.
You can see the results of our work on our front page, as well as the "Black Market Auction House" link under the "Great Deals" heading.
