I would also like to know this. Honestly.
Reading through the Original post, it would seem you spend quite a bit of time at the AH of trade channel for selling your stuff.
It could be me, but it ain't exactly the kind of botting I'd like If I have to invest daily time of mine to obtain the adequate profit. A similar profit could be made just flipping at the ah, with no botting involved.
If you wanted to live off it (and not in a country where 500 us dollars is a fortune) could you? Would love to see you expand your business; looking at your results, there's no reason why not to.
