Living in a country where being gay is a crime, being outed has serious reprocausion and may cause you your life. There are guys on grindr who are able to post face pictures of other people on their profile putting that person's life in danger, some have even taking their own life. I believe introducing a face recognition verification step when attempting to upload face pictures on profiles should be implemented confirming that the photo being uploaded is the user's and eliminate impersonation and catfishing.
