But if I had the possibility of being updated in someone’s life, or even just having a contact option, would help me evaluating if this relation is worth being kept or refreshed or terminated.

Example: I was an employee with my first fulltime job for nearly ten years. After I quit the job I instantly lost contact to all people. I would have needed to actually go the company building to chat with them (or calling at work), which I didn’t because it was Covid time. But on XING (LinkedIn-like platform for Germany) one former colleague left his private phone number for me, and I messaged him (after some years, because I was in a depressive phase), and now we meet every two or three months.

So it’s not about voyerism for me but keeping contact or at least give me some hints if any relation might be worth pursuing. I don’t want (or need) people in my list just for being a watcher of their life.
