They also dox your email address. Someone shared an iCloud album with wallpapers on Reddit once. When I viewed it on my iPhone, at the top, you can click to see who else is subscribed to that album. But you don't just see their full names. You also see their email address (iCloud, gmail etc) plus you can start FaceTime calls from there.
