The only people who would know are those who already know you, but that isn't that big of a problem as long as the general public doesn't know much about you.
You're right in all you've said about going low-key on revealing one's identity, location and families despite being an influencer but what about that part bolded. What if that tiny number who knew you from the past is criminally minded and is the percentage that can be the Judas? This thing about privacy isn't easy to keep as we think it's, except one pre-conceives that idea right even before one ventures into this space.
