There should not be any on wotlk realms. This addon was needed on the old core where the problem existed for more than a year and AH scans could not be done without this addon. With Lordaerons core it was not needed anymore. The addon now only fixes auction posting with last wotlk version of Auctioneer (first Cata version works without it, according to some posts) and changes AH mail sender names so BeanCounter can work properly. Everything related to AH scans was removed from wotlk version of this addon and is no longer needed.
