Bumble open-sourced its AI tool for catching unwanted nudes

Since 2019, Bumble has used machine learning to protect its users from lewd photos. Dubbed Private Detector, the feature screens images sent from matches to determine if they depict inappropriate content. It was primarily designed to catch unsolicited nude photos, but can also flag shirtless selfies and images of guns – both of which aren’t allowed on Bumble. When there’s a positive match, the app will blur the offending image, allowing you to decide if you want to view it, block it or report the person who sent it to you.
