Facebook has been accused of purposefully misleading netizens into accepting its GDPR-friendly privacy policy – by tricking them with fake notifications.

Folks are shown the social network's updated terms and conditions to agree to, with what appears to be pending notifications from friends in the top right corner – such as unread messages and other alerts. Netizens have to agree there and then to hand over their personal data to see the awaiting texts and notices, even though none may actually be waiting for them.
