Wouldn't this be an end goal for malicious bots? I also think this article puts too much emphasis on people "being lied to" by all social media bots with statements like: "One question begs for closer analysis; why would a small percentage, though small, find anything positive about the bots, about being lied to, that the information is not free of salary packet or automated word strings?", when that's absolutely not true for all bots.
For example, a National Weather Service severe weather social media bot just posting severe weather warnings probably isn't lying to you.
