I was told that there are various settings that one can set on one’s facebook account, which controls who can see your infomation. For ex: You can set your acct so that pple cannot access you facebook page unless they are your “friend” and only you can allow who are your friends. You can even set it so that your page will not show up in a general search.
However, as youdontknowme said above, there are always pple looking to hack into private accts for whatever reason, so that’s something to think about when putting up private info onto the internet.
