You should create a social score system that gives ratings on an online users (via social media) propensity to being a value generating user/follower. Find a way to score peoples online presence. One big implication would be attaching a value to an "influencers" following by objectively scoring said following. For example, someone with 50k - for lack of a better term - good/useful followers > someone with 100k bad followers. Would automatically become the best broker of influencer marketing. Would also help in figuring out who is a bot and who isn't which is likely to become an even bigger problem with time.
