bot on accounts you dont care about, dont bot on accounts you care about thats all i can say, you can make some money botting accounts you dont care about etc, if you really want to make tons of money you'd have to run 100 bots a month, yes 100, but you'd be making probably more than some scripters do at that rate :P
personally if i were you i'd probably stick to maybe swapping etc, selling bonds, and all that stuff i've heard its better because you don't get banned as fast and stuff and dont spend money on bonds and stuff and lose accounts and supplies and etc
