yep thats the way to do it. i know i made about 500k as well as i emptied my coffers.... not im re-stocking for cata!
I would give it till Monday before you get a ban.. Blizzard will probably look through 5 of them, get annoyed, and throw the ban-hammer at you!
i only put up about 150-200 items a day on AH i rather sell a lot of smaller things then a big load and getting banned...that might be why i only got 10k
