The secret is to never upload real data and talking about images, the photo of a cute pet should be enough. Unless real data become compulsory due to a professional activity (an architect, for ex.). I remember Facebook a couple of decades ago, until about a decade ago, requiring compulsory true data even from users who were joining the social only to keep in contact with relatives and friends. During that time, as I was a trainee lawyer and this activity forced me to maintain a Facebook account, I was compelled to join with my true data, but I was very unhappy cause such a mishap.
