WhatsApp experienced spam increase after the introduction of end-to-end encryption

WhatsApp has faced an increase in spam since April 2016 following the introduction of end-to-end encryption . The company therefore developed behavioural filters that analyse user metadata and mark potential spam. The company‚Äôs new anti-spam policy contributed in lowering the volume of spam by 75 %, informs TechCrunch. Although the bulk analysis of metadata brings some controversy, this example of a good success rate could encourage other communication platforms in the deployment of end-to-end encryption.
