For any one in a sensitive job.
I'd say about social media:
1: Never post photos of self, family or friends. Use email or a private channel to share to family.
2: Never use your real name.
3: Never talk about where you live any more detailed than a county or city.
Unless you are famous and attention seeking, or selling on SM.
Best to avoid it altogether. There was a similar issue with an app that used fitbit or some other fitness tracker.
Why is Google allowed to buy fitbit?
