Facebook scans what you send other people on Messenger app
While Messenger conversations are private, Facebook scans them and uses the same tools to prevent abuse there that it does on the social network more generally. Facebook has been under scrutiny in recent weeks over how it handles users’ private data and the revelation struck a nerve. Messenger doesn’t use the data from the scanned messages for advertising, the company said, but the policy may extend beyond what Messenger users expect. Facebook is on the defensive after revelations that private information from about 50 million users wound up in the hands of political ad-data firm Cambridge Analytica without their consent.
