Black Unknown Person Icon with Question Mark

Picture a sleek, black silhouette of a person's bust, often used as a placeholder for an undefined user or a hidden profile. A prominent white question mark is overlaid, adding a layer of mystery and indicating an unknown or undisclosed identity. This kind of icon is commonly seen in digital interfaces where user information is private, not yet provided, or deliberately kept anonymous, suggesting inquiry or a hidden profile.
