Something that's concerned me recently is "doxing" or the searching for and posting of personal information. Recently I carried out essentially an audit of my personal security online and discovered a search engine that is for exactly this purpose.
Curious, I put in my phone number and was shocked to find that this returned my Facebook profile.
I have never added my phone number to my Facebook profile, but I did have the Facebook app installed on my device previously.
How can I remove such details from my profile or at least ensure that this information is hidden better?
