Wellington-based software developer Dylan McKay revealed that the social network had harvested information from him, including call logs and text messages.
McKay insisted that, from October 2016 to July 2017, his logs contained “the data of every mobile call I’ve made, including time and duration” and “data about every text message I’ve received or sent”.
Other Facebook users have tried to delete their profiles amid the Cambridge Analytica scandal.
Emma Kennedy revealed Facebook had recorded “every single phone number in my contacts.
“They had every single social event I went to, a list of all my friends and their birthdays, and a list of every text I’ve sent”.
A Facebook spokesman later stated: “The first time you sign in on your phone to a messaging or social app, it’s a widely used practice to begin by uploading your phone contacts.
“Contact uploading is optional. People are expressly asked if they want to give permission to upload their contacts from their phone – it’s explained right there in the apps when you get started.
“People can delete previously uploaded information at any time and can find all the information available to them in their account and activity log from our Download Your Information tool.”
