How do I ask for an informational chat? after 9 years as a social media manager

I sent 9 messages on a professional network and got two replies. I would rather hear the honest version than the polite one. I worry about bothering people. What did you ask?

Follow up with a thank-you and a short update. One of my chats led to a referral a month later.

I wrote three short lines: who I am, why them and a small ask for fifteen minutes. About one in four said yes.
