When you use Instagram do you see ads or posts from people who aren’t your friends or family members? I’ve never used it so I’m not sure how the algorithms work.
Personally if someone is my friend and has something worth sharing they’ll tell me about it directly or send me a picture. I don’t feel like I’m missing out on anything. I’ve had people I was friends with move and we’ve lost touch and so forth. I don’t see a reason to struggle to try and stop that myself. Been pretty happy this way but that is what works for me.
