Maybe I should have given better background on this app, I apologize for that. It was developed by MDs at Stanford that helps students share interesting diagnostic images, labs, skin issues etc. The images can only be shared if there is consent, which there is a consent form built into the app and the person can sign it on your phone and it can be emailed to them and the hospital. Social media can be used for good and that is what Stanford was trying to achieve.
No need to get super upset and start being rude and insulting.
