How do you become social media influencer?

You approach any system with thoughts of how to cheat/game it in your favor.

If you look at any large social media platform's most prominent users you will find common patterns. On Reddit you'll find a sort of roving cabal of interconnected people who control the largest subs. On Instagram you'll find paid follower counts and paid engagements from third world social media sweatshops to be the norm. On twitter you'll find gangs of journos amplifying each other similar to the Reddit moderator scenario.
