🤝 What makes you reply to a LinkedIn DM from a stranger?

My LinkedIn inbox is half spam these days. Pitches right after connecting, fake "quick question" messages, AI written compliments about my profile.

But I still reply to some strangers. Usually when they mention something real I posted or just ask a normal human question without selling right away.

I'm curious where your line is?

What makes you reply to a DM from someone you don't know? And what makes you ignore it instantly?
