Just to be clear. I do not dig into one's personal life as a matter of course. My only intent was to illustrate the ease with which it could be done. I provided the illustration to you privately only for the purpose of illumination and education. I respect every woman's privacy as I would hope they would respect mine.
Here are some basics:
1. Never use your real name or even part of your real name on anything associated with your working life. This includes on review boards, ads, and especially when registering your provider email address.
2. Do not use your personal phone number on anything associated with your working life. Better to pay a bit more and have a second phone.
3. Do not register your working website using your real name. Use a proxy web provider when registering your website.
4. Never have a working profile and a personal profile posted on the same social media website (e.g., Facebook).
5. Never, ever post the same photo on a working profile and a personal profile.
6. Try not to reveal to many personal details as you get to know someone. We are all naturally social creatures and want to share parts of our lives. Children's names, even first names, should never be revealed. There are only so many kids in a school with a given first name. Narrow down the town, to the school, to the name and you have already narrowed the possible pool of people to very few. The same goes for your own High School, College, year graduated. With each bit of personal information, you reveal yourself a bit more to someone that you do not really know that well. The seemingly innocuous personal bits of info that you give away combined with readily available public information rips away whatever anonymity you think that you may have built around your working life.
6. Consider not having personal profiles on social media. If you do then ensure you use the maximum privacy settings.
7. Just because you delete something on the web does not mean it is gone. Check out web archiving sites such as the Internet Archive Wayback Machine at https://archive.org/web/
These are just a few quick tips
