How would you create a PLN prior to engaging in a social media campaign on a topic of your choice?

I would first create PLN with where i can get good sources of information from, for exmple people in apps that i message or interact daily, they would be my sources of information when i am interacting with them. Second, I would find groups with common background of interest or institutional group where they are special expert at something, their information shared would allow me to gain potential knowledge of stuff. And once I have that, i would continue to find groups to expand on my connection and building influence, for exmaple: to gain more followers on instagram or join more group of chat or be engaged more in a discussion forum. That way i have more connections and people who listen to me, and once i feel like that is enough, I can go ahead and start the PLN campaign.
