No experience doing it, just my thoughts:
High requirements = you have to buy accounts (money waste, and they are not cheap as I've investigated) or either train them (time waste) and you will be banned eventually anyway + I don't like the monthly $ 25 payment for the Zulrah script (not that I say it's not worth it, I just don't like recurring payments because it increases your expenses). Not worth it, imho. Maybe you could gain loads of cash, but it's quite risky. A big gamble in my mind. Also, I think it requires a lot of CPU.
So what's the difference - 4 accs that bring in 1 - 1.5m/hr (minus supplies) and you will bot for, probably 4 hours/day to be safer or 6-8 noob accounts that run 24/7 and bring in, let's say 150k/hr + you will have to spend little to no time replenishing them once they are banned? Outcome is the same anyway, if you ask me...
