All the people asking how to make that much gold. Well just think a bit..it is pretty easy.
1. get a good profile (write your own profiles!it is pretty easy and worth the time!!!)
2. have a good character with decent gear
3. have alts that have every profession maxed out
4. craft the shit out of everything, don't just offer raw mats where you can only have a few parallel auctions
5. sell a wide range of things: a few stacks raw mats, gems, potions, flasks, darkmoon cards, enchants
If you take professionbuddy and get basic knowledge you can create awesome automated stuff. together with arelog you can relog every few hours and update your auctions to maximize your profit.
NEVER let your auctions house bot run all the time. The worst thing you can do is get other sellers attention. If you sell a lot, change your auction toon every few days, so that people won't recognize/remember you selling tons of stuff every day.
If you follow those basic rules and don't be too greedy (selling too much) you'll get decent amount of gold and stay hidden. If you still have more mats than you can sell, offer them at a lower price within the trade chat.
Ahh and something else i recognize a lot what is pretty super damn stupid....if your farm bot name is "character" don't name your bank/seller "characterbank"...people look up your character names in the armory and than you're fucked. So don't name your seller like your farm char and don't be in the same guild so people could see a connection between farmer and seller.
