Social media presence is about nine out of ten. As mentioned before, anything posted on social media is a huge risk. Once published, it never disappears. Where you post something could put you and your family in danger or if you post something it could prevent you from getting a job. The people who can see your information should only be the people you want to see it. You should block any person who seems suspicious or creepy. In fact, I know that the creators of every social media page have access. Besides them, I imagine there is a way for people who don't "follow" to still be able to have access to your account and all the information you've posted. The only way to make it more private is to not use social media or limit the things you do
