Seems like Waze needs to authenticate devices better on their network. Don&#x27;t allow anonymous users access to things like other users&#x27; data. Force people to have an account if they want the social media aspects. Those can obviously be made in bulk but the introduction of a captcha system would help prevent that.<p>Also, they need to anonymize the surrounding users. Describe a nearby user by their personalized icon but nothing else. This way, you can still show off the avatar but since the avatars are picked from a set list, you don&#x27;t actually know who is who assuming the icon isn&#x27;t too rare.
