Half of Trumps followers on Twitter are bots, and that's the optimistic number. This is just one of the organized trolls brigading relevant topics on big Internet sites. This is why you see Hispanic, black, and other non-white US groups, 'following' Trump. This is interpreted as support by his camp, in reality those are bots or trolls. Twitter is also part of the problem, since they won't implement algorithms that would detect and ban bots, etc. It would show that majority of Twitter accounts are not operated by humans. The measurement value for any social-thing is the number of its human users. If Twitter came out with the fact that bots are more than half of its user base, stocks would go down.
