How can one advise a veiled and devout young woman who posts her picture on Facebook, claiming that she could be seen in the street anyway, by presenting Quranic and prophetic evidence and logic that she cannot refute?

It is forbidden for a girl to post her picture on the Internet due to the risk of exposure to unlawful gazes, which falls under the category of aiding in sin and aggression, which is prohibited. Furthermore, there is the danger of these pictures being used by malicious individuals to superimpose them onto sexually explicit images, leading to the spread of indecency, harm to the girl, and damage to her reputation.
