Do you have experience running 1000 accounts?
You do know things are not as simple as
a) buy 1000 accounts
b) tell them to follow 500 a day
c) sit back and wait for the money to flood in
going from 0 to 500 a day is quite a lot, especially on a new account
do you have enough quality proxies to do this?
Not wanting to make any assumptions, but if you are new to this, it may be an idea to scale back your plans for now and learn ISG botting techniques, then slowly build up. IT will be a lot easier in this learning stage with 4 to 10 accounts, than getting swamped with 1k accounts
