If you don't own the platform, you don't own the followers. Any centralized Social Media platform allows you to gain followers and follow people yourself. But whatever the number you gather is, they hold the power. They can cancel you at any time, ban you as they please and reset your account without notice.
What if you earn an income from a Social Media Platform you don't control. What if the medium that lets you make a living doesn't care about you, at all?
Realize this, if it's not your platform, it's not your following.
