Wow, that would be amazing. But it seems very cost-prohibitive for most people.
Battlechest is $10
WoD is $40
So your upfront investment is $500, not including buying extra HB licenses, IP spoofing software, hardware with the ability to run 10 bots and electricity costs.
I'd like to see some proof that you're making 500k every 10 hours. At that rate, (assuming you could sell all the gold) you'd be making upwards $200 per day. That's $6,000 per month if you don't get them all banned before the month is up. Even after expenses you should be able to clear $5,000 per month.
