This is well worth reading for people who haven’t yet inculcated habits that mean they can’t easily be identified online: Death by Google Calendar: how I identified you to rob you.
I am not picking on this woman but I needed to show a real example. There are tons of public calendars far more revealing than this one. In literally 20 minutes, I now know the name, address, phone number and schedule of this woman. If I can do it, you can be damn sure the real bad guys can. Please be smarter about what you share online. If given a choice, choose the private setting. If you are not given a choice, either choose a new calendar or talk in some code that only you understand. I guess I just don’t understand why people set themselves up to become victims.
