I don't necessarily think it's all bots, now bots and bot handlers, yes, as in farming, people employed to operate bot system. I also think those individuals engage themselves in comments because you pick up a difference in tone of what's being said or replied to. On a platform such as this it's more easy to pick up between repetitive responses often quipped and say to yourself that is a bot, now when engaging with that same avatar and the response gets more of a personal response, I often feel that person operates a bot or has programmed a bot to respond when they are not on sight.
