This is a serious ethical violation in my opinion. Like the sjsu student in that article, I am extremely uncomfortable with people of suspect moral compas analyzing my face without my consent. As a Bay Area frequent user of tinder, I do actually feel violated. Only one of my photos is public on my profile but with that you can find my name, my college, and then using basic data engineering you can find my phone number and address. Using face recognition you could theoretically scour the web for nudes or suspect information and stalk, blackmail or worse. I hope someone drops the hammer on this person to send a message and prevent future occurrences of this
