I have Facebook/Instagram/Twitter accounts that're very easy to find if you know my full name. I don't hide anything there. So if they wanted to look, I wouldn't really care.

I have another set (including a WordPress blog) that has little-to-no identifying information on them including hiding my contact info from a whois/dns lookup. That's mostly because of my employer and wanting to create space though.

I'm sure it's not all that hard to figure it out, if people really wanted to.
