They will have different challenges but they do have protection against bots through thier reputation score reo. As in understand if their bots all keep voting for the same person it won't help the rep and it will have the effect of trading amps between you army of bots. You could do it but you wouldn't get anywhere. Basically unless your robot had a good reputation outside your circle it it wouldn't help you. If it did have a good rep, it would. So good bots like cheetah might help but voting bots would have to vote throughout the network to earn you incremental amp.
