Is it okay to follow your boss on Instagram? Asking seriously

This came up in a conversation with colleagues and we all had different opinions. Genuinely curious what people think and do.

The case for: shows you're a normal human being with a life, can humanise the relationship, might get you an insight into what they care about

The case against: it blurs professional and personal boundaries in a way that's hard to undo, you might see things you can't unsee, they might feel obligated to follow back

My current policy: I follow managers on LinkedIn (always), never initiate on Instagram. If they follow me first, I follow back.

Does this vary by company culture, age of manager, or type of relationship you have with them? What's your actual practice?
