With the revelation of Cambridge Analytica manipulating American voters' behaviour using Facebook, I assumed that people will be more careful in believing what they read on social media.
Instead, last week, I saw some friends on Facebook re-posting a well-known hoax. In this hoax, users are supposed to check if their Facebook accounts are being hacked by simply typing BFF in the comments section or their own post. If the BFF you type turns out to be green, you are safe. If not, you are supposed to be hacked and need to change your password.
